"Let me just say that — that any public official — no matter whether it be the attorney general or anybody in public office — whenever you feel that you have lost your effectiveness or may be losing your effectiveness to the detriment of the job that you do, even though you're a good, honest, sincere, hardworking person, you have to evaluate that and make a decision," Manchin said. 

"And I think we're at the time now where decisions have to be made."

Manchin's comments add his name to the list of lawmakers who have argued that Holder should think about resigning in response to the revelation that that the Department of Justice had obtained phone records of Associated Press journalists in order to find the source of a leak about a foiled terrorism plot. Holder recused himself from signing off on that investigation, but lawmakers have maintained that he should still step down.

"I just think that, basically, in light of what is going on in the country, and everybody looking at it, it might be the most well intended person with the best of intentions, but if they're not being effective and they're not being received, how effective is it and how good is it for the — for the country?" Manchin asked.

Top Obama administration officials, however, have said that Holder is unlikely to leave his post soon. Senior Obama administration adviser Valerie Jarrett said Thursday that Holder would remain at his post for "quite a while."

"Obviously, I know the president pretty well, and I know the attorney general very well, and he will be in his position for quite a while," Jarrett said in an interview with HuffPost Live.
