Eric Holder 'Not Sure' If He'll Stay On As Attorney General If Obama Wins Second Term

WASHINGTON -- Attorney General Eric Holder said Tuesday he doesn't know if he'll stay in his job if President Barack Obama wins a second term in November.

"What my future holds, frankly, I'm just not sure," Holder said during a Senate Judiciary Committee hearing, when asked point blank if he plans to stay in Obama's administration.

Holder said that question is ultimately up to Obama. Pressed on whether he would stay if the president asked him to, Holder simply said he has enjoyed his time as attorney general but that "it's been a tough job."

"It is one that takes a lot out of you," he said. "Some have raised concerns about whether I was tough enough. I hope people will see ... [that I] stuck by my guns ... I've lost some, I've won more than I've lost. This has been the highlight of my career."
