Nunes accused someone in the DOJ of leaking the information after he and Rep. Trey Gowdy (R-S.C.) did not agree to Justice officials' offer to answer questions from lawmakers in a briefing.

"Now if you look at what happened on Friday night, probably the mother of all leaks, of all time, to two major newspapers, that came out Friday night. Now, had Mr. Gowdy and I went to that meeting, you can bet they would have tried to pin that on us," Nunes told Maria Bartiromo on Fox News's "Sunday Morning Futures."

"We had what I thought was a productive meeting, and then, after that meeting, they've done nothing but leak and leak and leak," Nunes continued.

"Now, we don't know exactly who it is over at the Department of Justice or the FBI. I'm not pinning any blame on people. But we're not going to go to another meeting where we don't get documents and then the meeting leaks out."

Wow, word seems to be coming out that the Obama FBI “SPIED ON THE TRUMP CAMPAIGN WITH AN EMBEDDED INFORMANT.” Andrew McCarthy says, “There’s probably no doubt that they had at least one confidential informant in the campaign.” If so, this is bigger than Watergate! — Donald J. Trump (@realDonaldTrump) May 17, 2018

The FBI sent the informant into the campaign after they received evidence that two Trump campaign advisers were linked to Russian contacts, according to The New York Times.

Trump announced on Sunday that he will demand the Justice Department look into the matter.
