Colorado’s U.S. attorney, Jason Dunn, plans to resign as the Biden administration prepares to appoint new top federal prosecutors.

Dunn, an appointee of President Donald Trump, said resignation will be effective Feb. 28. He joined the U.S. attorney’s office in 2018, and he declined to speak of his future plans.

“Serving as United States Attorney has been the greatest honor of my professional life,” he said in a written statement. “Public safety was always our number one priority.  We took on violent crime and drugs with ferocity, focusing on gun crime, gang violence, and narcotic traffickers using new and innovative techniques.”

Dunn noted that his office and federal law enforcement helped ensure a free and fair election in November.

“We established an election security team that helped deliver the most secure election in Colorado’s history,” he wrote. “… At the end of the day, Coloradans could vote freely and be sure that their votes were counted accurately.”

Dunn is one of more than 50 top federal prosecutors who were asked to resign — a normal occurrence in changes of U.S. presidential administrations.

Dunn’s successor will need to be confirmed by the U.S. Senate.

Colorado’s Democratic senators, Michael Bennet and John Hickenlooper, have recommended possible replacements, including Denver City Attorney Kristin Bronson, Assistant U.S. Attorney Hetal Doshi and Cole Finnegan, a former Denver city attorney who served as chief of staff to then-Denver Mayor Hickenlooper.
