Former Clinton adviser Mark Penn said Monday that former FBI Director James Comey's firing "triggered" Andrew McCabe, prompting the agency's former deputy director to help launch an "out of touch" probe into President Trump.

McCabe recently told CBS News' "60 Minutes" that Deputy Attorney General Rod Rosenstein was "absolutely serious" about recording Trump following Comey's ouster. He also confirmed in the interview that he ordered an obstruction of justice probe against the president.

"I was very concerned that I was able to put the Russia case on absolutely solid ground in an indelible fashion that were I removed quickly and reassigned or fired, that the case could not be closed or vanish in the night without a trace," McCabe told Scott Pelley.

Penn said on Fox & Friends that there was no predicate for the actions that McCabe took to investigate the president.

"[McCabe and Rosenstein] decided instead to hire a special counsel and put this investigation with a special counsel, with their friends, out of touch of the normal course of things, deliberately ... without any event justifying it," he said. "There was no crime."

Penn said McCabe wanted the investigation to proceed because they wanted to oust Trump, after being unable to invoke the 25th Amendment.

Trump reacted to McCabe's interview Sunday night, tweeting that he was telling "so many lies" and that his story is now "even more deranged."

Penn added that McCabe and Rosenstein should be called to testify under oath, because neither of their accounts are fully vetted.
