BOMBSHELL: McCabe says FBI told GOP lawmakers in 2017 they were investigating Trump -- and none objected

Former deputy FBI Director Andrew McCabe on Tuesday dropped a major bombshell when he claimed that the FBI told a bipartisan group of lawmakers in 2017 that it had opened an investigation into President Donald Trump -- and none of the Republicans in the group objected.

In an interview with NBC's Savannah Guthrie, McCabe said that the FBI told the bipartisan "Gang of 8" members of Congress who receive regular briefings on classified information that the bureau was launching an investigation into Trump's behavior after the firing of former FBI Director James Comey.

"No one objected," McCabe said of the senators' reactions. "Not on legal grounds, not on constitutional grounds, and not based on the facts."

McCabe also told Guthrie that, in May 2017 when it began its investigation, the FBI believed that it "might be possible" that Trump was working directly for Russia.

"You have to ask yourself why any president of the United States might not want to get to the bottom of Russian interference in our election," he said.

McCabe also told Guthrie that "we had information that led us to believe that there might be a threat to national security, in this case, that the president himself might, in fact, be a threat to United States' national security."
