FBI Deputy Director Andrew McCabe said former FBI Director James Comey personally informed him about the loyalty pledge conversation President Trump had with Comey, according to a new report.

McCabe said during his private testimony with the House Intelligence Committee earlier in the week that Comey had shared details of conversations he had with Trump shortly after they happened, CNN reported Thursday.

McCabe told the congressional investigators that Comey informed him Trump had asked for Comey’s loyalty, CNN reporter Manu Raju said on CNN Thursday evening.

That would appear to substantiate Comey's testimony before the Senate Intelligence Committee in June, during which he claimed Trump had requested his loyalty at a White House dinner in January.

“I need loyalty, I expect loyalty,” Trump said, Comey claimed.

Although Comey said he initially didn’t respond, Trump brought up the subject later in the evening. Comey told Trump he would give him “honesty loyalty.”

Trump has denied Comey’s claims and said he never made such a request.

Comey was ousted from the FBI in May. The Trump administration has provided numerous explanations for firing Comey, including that the president had lost confidence in Comey's ability to lead the FBI and that Comey had not handled the Hillary Clinton email case properly.

McCabe also told investigators this week how the FBI may have used the findings of the so-called “Trump dossier,” which contained scandalous and unverified claims about Trump's ties to Russia, and about potential bias that existed among FBI staff members.

Earlier this month it, was revealed that Peter Strzok, a top FBI counterintelligence agent who was part of special counsel Robert Mueller’s Russia inquiry team, had exchanged anti-Trump and pro-Hillary Clinton text messages with his alleged mistress, Lisa Page, a lawyer who had also worked for Mueller into the summer.

Strzok was also a lead investigator in the investigation into Clinton's unauthorized private email server.

Republicans have expressed concern that this bias could have influenced the FBI and Mueller's investigation into whether the Trump campaign colluded with the Kremlin in 2016.

The messages were revealed as part of an inspector general investigation concerning the FBI’s behavior during the 2016 election.

In total, McCabe spent over 14 hours testifying before members of the House Intelligence, Oversight, and Judiciary committees in two separate sessions. Several Republicans have called for McCabe's removal from office.
