Attorney General Eric Holder, a prominent member of the Obama administration since it began, will resign his post Thursday, according to multiple news reports.
The President is expected to announce the resignation this afternoon. Holder will stay on until his successor is confirmed, a White House official said.
Holder has long signaled he plans to leave the job by the end of this year, and has had several discussions with Barack Obama about his exit.
Among those mentioned as possible successors is former White House counsel Kathyrn Ruemmler, according to people familiar with the discussions.
Other candidates being considered by the White House are Solicitor General Donald Verrilli, along with Manhattan U.S. Attorney Preet Bharara.
The first African American attorney general, Holder is one of a few remaining cabinet members whose tenures date back to Obama's inauguration.
