PORTLAND, Maine (AP) Maine’s top federal prosecutor is among those being asked to resign by month’s end by the Biden administration.

U.S. Attorney Halsey Frank confirmed to the Portland Press Herald that he has been asked to step down effective Feb. 28. He was appointed four years ago at the start of the Trump administration.

It’s fairly customary for the U.S. attorneys to leave their positions after a new president is in office, but the departures are not automatic.

In 2017, then-Attorney General Jeff Sessions asked for the resignations of 46 U.S. attorneys who were holdovers from the Obama administration.
