Jason Chaffetz raises the prospect:

Representative Jason Chaffetz, a Utah Republican, says President Barack Obama may face impeachment over his administration’s response to the Benghazi attack.
“They purposefully and willfully misled the American people, and that’s unacceptable,” Chaffetz tells me. “It’s part of a pattern of deception.”
Behind the scenes, he says, House Republicans are frustrated by the White House’s evasiveness, and the calls for impeachment will likely increase.
Chaffetz acknowledges that House speaker John Boehner is wary of moving too swiftly against the president, but the brash, 46-year-old conservative is tired of waiting for answers. He’s ready to issue subpoenas and schedule more hearings.
