Mark A. Klaassen has taken the oath of office to become the United States Attorney for the District of Wyoming, according to a news release.

“It is an honor to be confirmed as the next United States Attorney for the District of Wyoming," Klaassen said in a prepared statement.

"I am pleased to continue working with a talented group of colleagues, as well as our federal, state, and local law enforcement partners," Klaassen said. "Wyoming is a special place to live and raise a family. As United States Attorney, I am committed to sustaining efforts necessary to protect our communities and uphold the rule of law."

He cited challenges for justice including violent crime, illegal drugs, prescription opioid abuse, and the abuse of vulnerable citizens, Klaassen said. "Together with our law enforcement partners, we will make a difference."

He also thanked President Donald Trump and support of Sens. Mike Enzi and John Barrasso, and Rep. Liz Cheney.

Klaassen was nominated by Trump on July 21, and confirmed by the U.S. Senate on Nov. 9.

U.S. District Court Judge Alan B. Johnson administered the oath of office.

As U.S. Attorney, Klaassen is the top-ranking federal law enforcement official in the federal district of Wyoming. He oversees a staff of 42 employees, including 17 attorneys and 25 non-attorney support personnel.

 

The office is responsible for prosecuting federal crimes occurring in the district, including crimes related to public corruption, child exploitation, firearms, and narcotics. The office also defends the United States in civil cases and collects debts owed to the United States.

Former U.S. Attorney Christopher "Kip" Crofts resigned on March 10, the same day U.S. Attorney General Jeff Sessions asked for the resignations of 46 U.S. attorneys who were appointed during President Barack Obama's administration.

While asking for the resignations of U.S. Attorneys by a new administration was not unusual, the Associated Press reported Montana U.S. Attorney Mike Cotter said he was shocked by the unprofessional manner in which he and 45 other Obama appointees were asked to turn in their resignations by the end of the day.
