Content: Former President Donald Trump appointed Hur to the position in 2017 and he subsequently took office in April 2018. Upon his departure on Feb. 15, First Assistant U.S. Attorney Jonathan F. Lenzner will become the acting U.S. attorney. Hur did not provide a reason for his departure, but U.S. attorneys have historically resigned after a new president is sworn in, especially if it marks a political party change within the White House. The Biden administration has not asked any Trump-appointed U.S. attorneys to leave. In a statement, Hur expressed his gratitude for the opportunity, and to have helped "further the Office's proud legacy of pursuing justice with integrity, and without fear or favor." "For an attorney — especially a first-generation American like myself –– representing the United States is a weighty privilege and a dream job. I have been blessed to do so,” he added. During his time as U.S. Attorney, Hur brought forward a number cases involving public corruption, national security and cybercrime, violent crime and gangs, fraudand the opioid crisis. He also hired dozens of attorneys, increased the office's diversity, and improved its technology, physical space and processes among other changes, a release from his office stated. Perhaps the most notable charges were those brought against elected officials, public office holders and public employees, including former Baltimore Mayor Catherine Pughand former Maryland Del. Cheryl Glenn.
