Sen. Marco Rubio (R-FL) said that President Trump's inner circle failed him by not briefing him about the correct way to interact with the FBI.

Rubio said he hopes Trump's advisers are now advising the president about the appropriate way to deal with the agency.

"It's not clear why that didn't happen sooner, and it was a disservice to the president," Rubio said on Capitol Hill Thursday.

Former FBI Director James Comey testified to the Senate Intelligence Committee Thursday, expressing concerns about Trump's intentions during private conversations between the two of them.

The now-fired FBI director stated that the president may have intended to pressure Comey into putting to rest an ongoing investigation into former national security advisor Michael Flynn's communications with the Russian ambassador.

Senators also quizzed Comey on whether he knew of evidence that the Trump campaign had colluded with Russian officials in an attempt to influence the election. Comey, for the most part, declined to comment on that investigation in a public setting, saying it involved classified material.
