Career

Miller became a citizen of the United States in 2000 and voted in the 2000 United States presidential election for Vice President of the United States Al Gore.

In 2006, Miller was appointed to serve as an at-large member of the Montgomery County Democratic Central Committee and served in that position until 2010.

Maryland House of Delegates

After state delegate Craig L. Rice announced that he would run for the Montgomery County Council in 2010, activists in the Montgomery County Democratic Party called Miller to ask her to run. She initially declined to run, but changed her mind after talking with her husband. Miller won the election to represent District 15 in the Maryland House of Delegates, but assumed office a month early due to Rice's resignation to take office on the Montgomery County Council. Miller received support from fellow members of the Montgomery County Democratic Central Committee, who voted to recommend that Governor Martin O'Malley appoint her to finish the last month of Rice's term. Miller was the first Indian American woman to be elected to the Maryland Legislature.

    2018 congressional election

In May 2017, Miller told The Baltimore Sun that she would run for Congress in Maryland's 6th congressional district if John Delaney decided to pursue a campaign for governor. On July 28, 2017, Miller announced her candidacy in the United States House of Representatives election to replace Delaney, who said he would not run for re-election to instead run for president in 2020. In April 2018, Miller won a straw poll of Democratic activists in Western Maryland. During the election, she was endorsed by the National Education Association, the Sierra Club, EMILY's List, 314 Action, and Sen. Kirsten Gillibrand, Rep. Pramila Jayapal, and then County Executive Ike Leggett, among others.
Despite having received the most individual donations out of her Democratic opponents, Miller was outspent in the primary 13:1 by David Trone, the largest self-funding congressional candidate in U.S. history, and lost the primary to Trone by 9.3%, with 30.7% of the vote compared to Trone's 40.0%, and consequently did not advance to the general election. She won Montgomery County but this was the only voting district she won outright. Had she been elected, Miller would have been the only woman in Maryland's congressional delegation.

In February 2019, Miller was named the new executive director of Indian American Impact.
In January 2021, Miller filed paperwork to run for Congress again had Trone decided against running for a third-term. After Trone launched his re-election bid on May 7, Miller declined to comment on her 2022 plans.

Tenure

Miller was sworn in on January 18, 2023. She took the oath of office on the Bhagavad Gita, making her first lieutenant governor to do so.
In February 2023, Miller became the first woman of color to chair the Maryland Board of Public Works meeting after Governor Moore recused himself from a vote related to a contract between the Maryland Department of Health and Under Armour, a company he has financial holdings in. In October 2024, Miller and Comptroller Brooke Lierman presided over the Board of Public Works, marking the first time in Maryland history in which only women presided over the meeting.
Miller was an at-large delegate to the 2024 Democratic National Convention, pledged to Kamala Harris and served as a member of the DNC Rules committee. Miller traveled out of state to battleground state of Michigan in support of the Kamala Harris 2024 presidential campaign In the 2024 presidential election, Miller voted as an elector pledged to Harris.

Highway work zone safety

During her tenure, Miller has worked on issues involving transportation issues, including mass transit projects like the Red Line and Purple Line, and in promoting STEM education. In April 2023, following a car crash that resulted in the deaths of six highway workers, Governor Moore appointed Miller to chair the Work Zone Safety Work Group. This group was tasked with developing policy recommendations to prevent future work zone accidents. Under Miller's leadership, the Work Zone Safety Work Group proposed several key measures, including modifications to existing state laws to authorize the use of unmanned cameras in work zones and increased penalties for speeding in these areas. These recommendations were incorporated into the Maryland Road Worker Protection Act of 2024, which Miller testified for in both houses of the Maryland General Assembly. The bill was subsequently passed and signed into law by Governor Moore. In early 2025, following implementation of the new work zone speed enforcement law, Maryland issued over 48,000 speeding citations in work zones within the first two months. During National Work Zone Awareness Week, Miller emphasized the law’s purpose, calling reckless driving “a dangerous weapon.” Following the resignation of Maryland Transportation Secretary Paul Wiedefeld in July 2025, Miller was tasked with leading a nationwide search for his replacement.

Substance abuse prevention

As lieutenant governor, Miller chairs the Maryland Overdose Response Advisory Council, which is involved with efforts to reduce overdose deaths and expand access to treatment. In this position, she has overseen the launch of a statewide overdose data dashboard to provide real-time data and guide policy interventions. In 2025, Maryland recorded its fourth consecutive year of declining overdose deaths in the state, which had also fallen to a ten-year low.
