Former acting FBI Director Andrew McCabe told CBS News that the Department of Justice discussed whether there was enough support from members of President Donald Trump's Cabinet, including Vice President Mike Pence, to assemble the group to invoke the 25th Amendment to remove the president from office.

He also admitted that he ordered an obstruction of justice investigation into Trump in order to keep the Russia investigation alive after Trump fired former FBI Director James Comey.

Here's what he said

McCabe was fired on March 16 by then-Attorney General Jeff Sessions.

In a preview clip that ran on Thursday's edition of "CBS This Morning," McCabe told CBS "60 Minutes" host Scott Pelley that the idea that somehow Trump colluded with Russia "was something that troubled me greatly." He said the day after he met with Trump, he told the team investigating possible collusion between the Trump campaign and Russia to try to figure out what their next steps should be in order to keep the investigation going.

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 or reassigned or fired, that the case could not be closed or vanish in the night without a trace. I wanted to make sure that our case was on solid ground and if somebody came in behind me and closed it and tried to walk away from it, they would not be able to do that without creating a record of why they made that decision.

Although it wasn't included in the clip, Pelley told the "CBS This Morning" panel that McCabe had told him, "There were meetings at the Justice Department at which it was discussed whether the vice president and a majority of the Cabinet could be brought together to remove the president of the United States under the 25th Amendment."

Pelley clarified that the DOJ had not specifically asked Cabinet members whether or not they would support such an endeavor, but "they were speculating, this person would be with us. That person would not be, and they were counting noses in that effort."

The interview with McCabe is scheduled to be broadcast on "60 Minutes" on Sunday at 7 p.m. ET on CBS.
