The FBI has handed Congress two copies of notes from its interview with Hillary Clinton about her private email server, but according to the chairman of the House Oversight Committee, the two sets of notes aren’t consistent with each other.

“The … thing that is stunning to me, which I found out last night, is the FBI gave us one set of documents. Then we asked them, and they … gave us a second copy in a classified setting. But they’re different,” said committee Chairman Rep. Jason Chaffetz in a Monday morning interview on MSNBC.
