Rep. Mike Pompeo, R-Calif., said Monday that Congress still hasn’t seen “thousands” of documents from the Obama administration related to the 2012 attack in Benghazi, Libya, and accused Hillary Clinton of stonewalling lawmakers’ effort to investigate.

“There are scores and scores of documents, thousands we understand that we have not yet seen,” he said on Fox News. “We don’t know the contents of them. We can be pretty sure they weren’t just about yoga and schedules.”
