Funk worked for the United States Department of Justice under U.S. Attorney Patrick Fitzgerald for 10 years. During his time with the DOJ, he prosecuted numerous high-profile cases, including those of mobsters, white collar criminals, Roman Catholic priests and deacons, and company CEOs.As an Assistant United States Attorney, Funk also prosecuted Joey "The Clown" Lombardo, Frank Calabrese, Sr. and other high-ranking mobsters as part of Operation Family Secrets, an FBI investigation into 18 homicides and various other crimes committed by the Chicago Outfit between the 1960s and 2000s. The investigation was considered one of the most extensive racketeering cases of its kind and was labeled as one of the most important criminal investigations in American history by National Public Radio. During closing arguments of the trial, Calabrese told Funk, "You're a fucking dead man." Calabrese and all of his thirteen co-defendants were convicted.
Funk also prosecuted former U.S. Marshal John T Ambrose for leaking information to mob figures about the location of a protected witness. It was the first case of its type involving a U.S Marshal violating the security of the Witness Protection Program. Ambrose was assigned to guard Nicholas Calabrese, the first "made" member to ever testify against the Chicago outfit. Ambrose was charged and later convicted with leaking information about Calabrese to other mob figures.
Funk also prosecuted mobsters Joseph Scalise, Arthur Rachel and Robert Pullia for their involvement in a conspiracy to rob cash from the First National Bank of La Grange in 2010. The three men, already famous for their 1980 involvement in the theft of the 45-carat Marlborough diamond from Graff's jewelry store, had planned to rob an armored vehicle at the bank and had stolen vehicles and stashed guns to use in the robbery. All three were convicted.
