Theory I heard was Nunes's former aid moved over to the White House on March 3. 2nd at NSC I believe. In this position he is in position to see what evidence the FBI had. And it was big. A FISA warrant has been in place since last fall covering two Russian banks in a money laundering scheme. Trump's son in law and possibly Trump were caught on tape talking to a bank I love how there are calls for Nunes to identify his source, he doesn't identify sources because he wants sources to feel safe coming forward to him, who was ex FSB and thus a surveillance target. A guy who was already a sanctioned individual. Nunes's guy flips out and Nunes goes running to the White house at midnight.

The 3rd is when Trump blew up about having a "tapp" on him. Nope it was on a Russian bank and they just caught talking about money on the Russian tapp

he doesn't identify sources because he wants sources to feel safe coming forward to him,

Doesn't work that way. His source is a White House employee giving him US intelligence product. He is a member of the oversight committee. If he told Jared or Trump they were on tape, it's obstruction of Justice. And this info will eventually be shared withe committee. The FBI knows about already.
