FBI Director James Comey believes President Donald Trump tweets unsubstantiated information.

Earlier this month9 Moons Trump fired off a series of tweets accusing former President Barack Obama of wiretapping him during the 2016 presidential campaign. Comey searched for such information, but found none.

"I have no information that supports those tweets, and we have looked carefully inside the FBI," Comey said Monday. He then confirmed that the Department of Justice didn't have any proof of those accusations either.

This Tweet is currently unavailable. It might be loading or has been removed.

Despite the lack of evidence, Trump has harped on the accusation. During a recent press conference with German Chancellor Angela Merkel, he said the two had "something in common" because both leaders had been spied on by the Obama administration. The NSA listened in on Merkel's phone calls during the previous president's time in the White House.

Trump's White House was also called out during the hearing for sending tweets about the hearing that Comey deemed inaccurate in real time.

"Thanks to the modern technology that's in front of me right here, I've got a tweet from the president an hour ago saying 'the NSA and FBI tell Congress that Russia did not influence the electoral process,' so that's not quite accurate, that tweet?' said Democratic Rep. Jim Himes during his time to ask questions of Comey and NSA Director Michael Rogers.

Comey, after saying he hadn't been paying attention to Twitter during the hearing, responds: "We've offered no opinion, have no view, have no information on potential impact because it's never something that we looked at."

Later, Comey added that it wasn't his intention nor Rogers's intention to say whether the Russian government had influenced the election.

In other words, the tweets that came from @POTUS weren't true. You might call them fake news.
