It is one thing to imagine a fictional world. It is another to repeatedly assert that something imagined is real. The first is the realm of the novelist. The second is that of a demagogue. https://t.co/ofhIb5QF2a — Adam Schiff (@RepAdamSchiff) May 25, 2018

Schiff’s attack on Trump comes a day after a group of lawmakers met with the FBI, Justice Department and intelligence officials about an FBI informant who worked on Trump’s campaign.

Democrats said after the meetings that there was “no evidence” that the FBI placed a spy in Trump's team. ADVERTISEMENT

"Nothing we heard today has changed our view that there is no evidence to support any allegation that the FBI or any intelligence agency placed a spy in the Trump campaign or otherwise failed to follow appropriate procedures and protocols," Schiff said on Thursday.

Schiff also said on MSNBC’s "Morning Joe" that the latest claim from Trump isn’t “spygate,” but “liegate.”

“The president said that there was wiretapping at Trump Tower. That was false. He said there was an unmasking conspiracy. That was false. He said that there [were] political spies embedded in his campaign. That is false,” Schiff said.
