Later hired as the Chief of Staff for the Office of the First Lady. Resigns after she upsets the President. Agrees to become the Director of Legislative Affairs in the Santos administration.

During the censure hearings, he helps facilitate a schedule delay which allows Leo McGarry to avoid potentially damaging testimony. Briefly hired as Deputy Chief of Staff by C.J. Cregg, where he helps orchestrate a Democratic vote on stem cell research that the Republican Speaker of the House has stymied.

While a political consultant, she is hired to be Director of Legislative Affairs, fulfilling Josh Lyman's duties while he is benched for causing a Democratic Senator to defect.

Other White House staffers

• Dolores Landingham : The President's first executive secretary and a close confidante dating back to his high school days. Her death in a car accident at the end of season two briefly shakes Bartlet's faith. Appears in flashbacks. Referred to simply as "Mrs Landingham" almost always by everyone, including the president.
• Deborah "Debbie" Fiderer : The President's second and final executive secretary, hired after the death of Mrs Landingham. Charlie arranges her first interview with the President against her own wishes, in which she is groggy from prescription medication and performs badly by confessing to being both a professional gambler and an alpaca farmer. Charlie later successfully pushes for her to be re-considered. President Bartlet learns the reason she lost her previous White House personnel job — she had defied the Director of Personnel by hiring Charlie rather than a wealthy Bartlet supporter's unqualified son — and, though appearing very quirky, he sees she is actually very smart and capable, he hires her on the spot.
• Margaret Hooper : Assistant to chiefs of staff Leo McGarry and C. J. Cregg. She is somewhat eccentric and often focused on the minutiae of life. Particularly devoted to and protective of Leo — frequently found snooping in on his private meetings — but she has a rebellious streak, so they are often at odds with their working styles. She is visibly pregnant in season 6, with no clear information about the father, and her baby is never seen on the show. After Leo is fired from his position by the President, she is convinced to stay on as C.J.'s assistant.

• Ed : White House staffer usually seen with Larry.

• Curtis Carruthers : Succeeds Charlie Young as personal aide to the President. Most notably carries the President out of Air Force One when he is debilitated by a Multiple Sclerosis episode.

Office of the White House Counsel

• Lionel Tribbey : The fourth White House Counsel of the Bartlet administration and the first to appear in the series. He has very liberal views and is animated and theatrical.
• Oliver Babish : The fifth and final White House Counsel of the Bartlet administration and the second of the two characters to be shown in that position during the series. Diligent and zealous, he first appears advising President Bartlet when the President is considering revealing his diagnosis of multiple sclerosis to the public. He appears connected to this plot-line into season three, then returns in season seven to participate in the White House's internal investigation into the military shuttle leak. He later decamps to a law firm in the wake of the outgoing Bartlet Administration and is later mentioned by Santos as a potential choice for Attorney General. He is described by Josh Lyman as "smart and tough".
• Ainsley Hayes : Associate White House Counsel. Conservative Republican from North Carolina. Graduate of Harvard Law School. After she soundly defeats and embarrasses Sam during a debate on the political talk show Capital Beat, President Bartlet tells Leo McGarry to offer her a job, which - after initially believing she is being rebuked - she thinks is either a joke or a terrible idea, but when seeing the White House staff in action in a crisis, leads her to accept the Associate White House Counsel's post. Primarily, she appears as a foil to Sam Seaborn, making him reconsider his position on policies. She briefly reappears in season 7, wanting to become White House Counsel for the Santos Administration with Josh planning on getting her a meeting with Santos.
• Joe Quincy : Associate White House Counsel who replaces Ainsley Hayes. Republican. He uncovers Vice President Hoynes's leaking of information during an affair with local socialite Helen Baldwin, ultimately leading to Hoynes's resignation. He is later asked by Toby to try and convince Supreme Court Chief Justice Roy Ashland, whom he once clerked for, to retire, a task he performs very reluctantly.

• Lieutenant General Alan Adamle : A three-star general in the USAF. Meets with Leo to discuss the International Criminal Court in episode 3.05 and stuns Leo by revealing Leo once bombed a non-military target and killed innocent civilians, telling a devastated Leo this story to lead to his view that "All wars are crimes".

Served with Leo in Vietnam.

• Lieutenant General Ed Barrie : Army Chief of Staff. He appears in episode 2.05 berating C.J. for reprimanding his intentions to condemn on TV the President's failure to ensure military preparedness before his retirement, but is left silent when C.J. tells him he is wearing a Distinguished Combat Service Medal he had not earned; later however, Bartlet says the General served his country bravely and would face no White House censorship of any of his views. Despite being identified as Army Chief of Staff, he is portrayed as a three-star lieutenant general.

• Colonel Mark Chase : Air Force officer who advises Leo on a crisis with Iraqi oil smugglers in episode 2.07, and monitors the Missile Defense Shield test in episode 2.12.
• CIA Director George Rollie : President Bartlet does not trust or like him, but as C.J. and Toby note in "365 Days", his pariah status is useful because it prevents the President from tearing down anyone else during tense situations.

• Bobby Dunn : Appears in episodes,,,, and ; apparently a State Department official.

Politicians

Frustrated at legislative setbacks in the House, Santos is on the verge of announcing a decision not to seek re-election, but instead is convinced by Josh Lyman to launch a long-shot campaign for the presidency.
• John Hoynes : President Bartlet's first vice president. Formerly Bartlet's rival for the 1998 Democratic presidential nomination, the two share a mutual resentment, which all of Bartlet's staff except Josh Lyman shared. Hoynes felt that Bartlet consistently disrespected and undermined him, while Bartlet saw Hoynes as feckless and incompetent, noting the amount of political deals and relationships he fumbled. Resigned from office while under fire for leaking classified material to a woman he was having an affair with, after she announced her intention to publish a tell-all book. A candidate for the Democratic nomination for the 2006 election, until it became clear he had no chance of winning. He has many similarities to Lyndon B. Johnson.
• Robert "Bob" Russell : President Bartlet's second vice president after the resignation of John Hoynes and a candidate for the Democratic nomination for the 2006 election. Recruits Will Bailey as his speechwriter and later campaign manager, who in turn recruits Donna. He is viewed by most of Bartlet's staff as bland and ineffectual.
• Lewis Berryhill : Secretary of State. He was nearly nominated by President Bartlet for the office of vice president after John Hoynes' resignation.
• Miles Hutchinson : Secretary of Defense. He often disagreed, loudly and at length, with the policy decisions of President Bartlet, which put him particularly at odds with Chiefs of Staff Leo McGarry and C.J. Cregg.
• Roger Tribbey : Secretary of Agriculture. Chosen to be the Cabinet's "designated survivor" during President Bartlet's first State of the Union address, later during the second term expressed concern about divided leadership when President Bartlet proposed invoking the 25th Amendment.

Federal legislative branch

• Senator Seth Gillette : Democrat from North Dakota. He threatened to run against President Bartlet as a third-party candidate on a more left-wing platform in the 2002 election.
• Rep. Jeff Haffley : Republican from Washington; House Majority Whip, 1997–2003, Speaker of the House, 2003–2007. He was known for repeatedly attempting to undermine the Bartlet administration and force it to cede control to the Republican majority, only to be outmaneuvered each time.
• Senator Howard Stackhouse Democrat from Minnesota. He ran a liberal third-party candidacy for the Presidency in 2002 but later endorsed President Bartlet.
• Senator Arnold Vinick : Republican from California. Republican candidate for president in 2006. Nominee for Secretary of State in Santos Administration. Senator from 1983 to 2007, was California's senior US Senator in 2006. Chairman of a powerful Senate Committee, and also served on the Foreign Relations and Environment Committees. Known for his Centrist views and refusal to compromise his personal ethics.
• Rep. Glen Allen Walken : Republican from Missouri; House Majority Whip, 1995–1997; House Majority Leader, 1997–2001; Speaker of the House, 2001–2003. During his time in the House, he was a staunch supporter of the military and veterans, proposed a $200 billion capital gains tax cut, and as an outdoor enthusiast supported the rights of gun owners. He became Acting President of the United States when President Bartlet temporarily relinquished power during his daughter Zoey's abduction. Later a contender for the Republican presidential nomination in the 2006 election, though he never appeared on screen in that capacity. Has similarities to Newt Gingrich.

State governors

• Eric Baker : Governor of Pennsylvania. He is widely tipped as a front runner for the Democratic nomination for president in 2006, but Baker's surprise decision not to run at the outset leaves the race wide open. When the convention is deadlocked, Baker enters the race from the floor as a draft candidate, but withdraws over fallout due to the discovery of his non-disclosure of his wife's depression. President-elect Santos nominates him for vice president following the death of Leo McGarry.
• Robert Ritchie : Governor of Florida. He was the Republican nominee for president in 2002 but was defeated by President Bartlet, who felt his dogged refusal to take a stance on any big issue made him unfit for office.
• Ray Sullivan : Governor of West Virginia. Republican nominee for vice president in 2006. Served as a U.S. Attorney and Attorney General of West Virginia before becoming governor.

Foreign officials

Campaign staff

The character reappears as Eric Baker's campaign manager for the 2006 Democratic primary, only to become an independent consultant to Republican nominee Arnold Vinick after Baker withdraws from the race. The change of political affiliations mirrored Ron Silver's real-world change of party affiliation, as the noted liberal actor campaigned for President George W. Bush in the 2004 presidential election.
• Josephine "Joey" Lucas : A political consultant and pollster who is often hired by the White House and Democratic campaigns. Usually, her interactions with Bartlet or Matt Santos are arranged by Josh Lyman, who has a crush on her early on. However, their relationship remains platonic and professional. Lucas first appears in the first season as the hard-hitting, sarcastic campaign manager for a Democratic House candidate whom the White House does not take seriously. She is then contracted to conduct a secret poll to determine whether the American public would accept the president's MS. Like Matlin, Lucas is deaf.
• Kenny Thurman : Joey Lucas's sign language interpreter.
• Connie Tate : A Bartlet-Hoynes reelection campaign staffer, she is a likable woman who quickly befriends Sam Seaborn. Often wins points by smoothing feathers ruffled by her acerbic co-worker Doug Wegland.
• Doug Wegland : A Bartlet–Hoynes reelection campaign staffer and speechwriter, he is acerbic and finds himself offside with Toby Ziegler but ends up winning the staffers' respect with his good ideas and staunch belief in them.
• Kevin Kahn : Former friend of Sam Seaborn. He is a staffer on Ritchie's 2002 presidential campaign who ends up humiliating Sam by leaking an attack ad that makes the Bartlet campaign look vindictive and stupid.
• Dylan Clark : Hoynes' campaign manager.

Santos campaign

• Louise "Lou" Thornton : an intelligent lobbyist described by Santos as having a "completely different take on the campaign" and by Josh as knowing "image stuff backwards and sideways", she only reluctantly agrees to Josh's request to join the Santos—–McGarry campaign as Director of Communications, when Santos agrees she can report to him directly. She acts as Josh's de facto deputy throughout the campaign, and at Josh's persuasion, accepts her appointment as Santos's Director of Communications.
• Ronna Beckman : Santos's personal assistant. She is present from the very beginning of Matt Santos's campaign for the presidency in season 6. In her final appearance, Deborah Fiderer trains her as Santos's executive secretary, warning her never to revoke the First Lady's walk-in privileges, even as the President is certain to request it. She has a relationship with another female staffer on the Santos campaign.
• Edie Ortega : Santos—–McGarry Deputy Campaign Manager for Strategic Planning.
• Lester : Santos—–McGarry Campaign Consultant.
• Bram Howard : Staffer, Santos—–McGarry Campaign ; Santos Administration counselor to the President. Moves into Charlie Young's former office on Inauguration Day.

Vinick campaign

• Sheila Brooks : Senator Vinick's chief of staff and Vinick–Sullivan campaign manager; She, like Vinick, is portrayed as level-headed and not overtly partisan. Often at odds with the more conservative voices in the party, she leaves the campaign weeks before election day to placate the Republican base. In her final appearance, Brooks is mentioned as possibly being hired as Chief of Staff to the Republican Senate Majority Leader. Having renewed her friendship with Vinick, she makes an argument that convinces the Senator that he should not run for president again—and that he should accept President-elect Santos' offer to become the next Secretary of State.
• Jane Braun : Vinick–Sullivan campaign manager after Brooks' resignation ; A far-to-the-right conservative activist who replaces Sheila to energize hard-core GOP voters. However, she disgusts the rest of the campaign leadership by attempting to make an election night issue of Leo McGarry's death. Her outspoken partisanship puts her at odds with Vinick, Sheila, and Bruno Gianelli.
• Bruno Gianelli :.
• Bob Mayer : Vinick–Sullivan speechwriter. Frequently mocked for his messy eating habits but extremely smart and effective, Mayer becomes fast friends with Gianelli. On election night, the two briefly discuss forming a consulting firm when Mayer firmly declares he is never going to become involved in daily governance, but Gianelli politely declines because the campaign life has worn him down and he plans to retire to his home in upstate New York. Along with Sheila, Bob advises Vinick to accept Santos' offer as the next Secretary of State.

He refuses to reveal his source, is accordingly held in contempt of court, and goes to jail.

• Owen Lassiter: A two-term conservative Republican president from California that defeated Newman for reelection. Lassiter's administration is seen with disdain by Bartlet and his staff for his conservative policies. In his post presidency, Lassiter collected dirt samples in jars from battlefields where Americans served. He also regularly called Newman and Bartlet to discuss issues of the day or former Presidents. Lassiter convinced a furious Newman to not publicly denounce Bartlet during the MS scandal. Comparable to Ronald Reagan.
• Glen Allen Walken : Republican from Missouri; House Majority Whip, 1995–1997; House Majority Leader, 1997–2001; Speaker of the House, 2001–2003. During his time in the House, he was a staunch supporter of the military and veterans, proposed a $200 billion capital gains tax cut, an outdoor enthusiast that supported the rights of gun owners. He became Acting President of the United States when President Bartlet temporarily relinquished power. Later a contender for the Republican presidential nomination in the 2006 election. Has similarities to Newt Gingrich.

Pets

• Bess: Glen Allen Walken's pug.
• Gail: C. J. Cregg's pet goldfish. A gift from Danny Concannon. In "The Short List", Josh Lyman tells Danny that C.J. likes "goldfish". Although Josh is referring to the snack crackers of the same name, Danny mistakenly believes he is referring to the aquatic creature; after giving C.J. the fish, Danny mentions that the pet-store owner had named it "Gail". On the DVD commentary track for Ep. 1.10, "In Excelsis Deo", Aaron Sorkin, Thomas Schlamme, and Alex Graves mention that the prop masters created a miniature Christmas ornament to place on the floor of Gail's fish bowl and that from then on, the prop masters often crafted tiny decorations related to the themes in a given episode. For example, when hostilities were escalating in India and Pakistan, the bowl contained a tiny bomb shelter.
• Henry: Amy Gardner's basset hound.
