U.S. Attorney for the District of Alaska Karen Loeffler said in a statement Monday that she submitted her letter of resignation to President Donald Trump.
Trump ordered 46 holdover U.S. attorneys from the Obama administration to tender their resignations immediately on Friday.

Obama signed Loeffler's commission on Oct. 16, 2009, elevating her to the state's top federal prosecutor after 20 years as an assistant U.S. attorney.
It is not unusual for a new president to replace U.S. attorneys appointed by a predecessor. Some presidents have done it gradually, but that's not always the case. The Clinton administration fired all 93 U.S. attorneys on the same day.
Loeffler said she has worked for the Department of Justice for more than 29 years. She was plucked from her position at the Anchorage District Attorney's Office in 1988 to help then-U.S. Attorney Michael Spaan prosecute lobbyist Lew Dischner and consultant Carl Mathisen in a North Slope Borough kickback and bribery scandal.
In 1989, Spaan hired Loeffler as a full-time assistant U.S. attorney. "It has been the career of a lifetime representing the United States in court and working with people throughout Alaska to enhance justice and public safety in our state," she said.

In the interim, before Trump picks a replacement, the acting U.S. attorney will be Bryan Schroder, said Chloe Martin, spokeswoman for the federal prosecutor's office in Alaska. Schroder is also the first assistant U.S. attorney in the office and chief of its criminal division.
"I am very proud of my career in this office, but even more of the fabulous lawyers and staff who work in the United States Attorney's Office for the District of Alaska," Loeffler said in her statement. "This community is well served by the dedicated members of this office."
