Kim joined the U.S. Attorney's office for the Southern District of New York in 2000. As an assistant U.S. attorney, he investigated and prosecuted a wide range of federal crimes including racketeering, murder, money laundering, securities fraud, firearms and narcotics offenses, tax evasion, and terrorism. He spent his prior years in the office in the organized crime and terrorism unit, prosecuting violent organized crime syndicates, including Asian gangs and the Mafia.
From 2006 to 2013, Kim worked at Cleary Gottlieb Steen & Hamilton LLP, where he was a partner in the litigation and enforcement group, focusing on white-collar criminal defense, regulatory enforcement, commercial civil litigation and international arbitration.[3]
Return to the U.S. Attorney's office
Kim rejoined the United States Attorney's office for the Southern District of New York as chief counsel in April 2013.[3] After becoming the chief of its criminal division in July 2014, he was promoted to Deputy U.S. Attorney in July 2015. When Preet Bharara was fired as U.S. Attorney in March 2017, Kim replaced him in an acting capacity, but had to be replaced in January 2018 because of a 300-day limit on acting U.S. attorneys.[4] Kim's term was notable for the continued prosecution of high-profile terrorism cases,[5][6] pursuing a prison term for Anthony Weiner following his guilty plea to a federal obscenity charge,[7] and for securing the conviction of Mehmet Hakan Atilla, a Turkish banker, on fraud and conspiracy charges in a billion-dollar scheme to help Iran evade American financial sanctions via Turkish banks, despite an investigation of the American prosecutors by the government of Turkey.[8]
On November 30, 2017, Kim announced the sentencing of Aharon Goldberg, Shimen Liebowitz and Binyamin Gottlieb, three organizers of the Kiryas Joel murder conspiracy who had tried to force an end to their intended victim's marriage under Jewish marital law.[9][10]
Return to private practice
In April 2018, Kim returned as a partner at Cleary Gottlieb Steen & Hamilton LLP.[11][12]
