Former CIA Director John Brennan might not be the only former national security official to have his security clearance revoked by President Trump.

Last night, the president tweeted a statement he attributed to Fox News host Sean Hannity saying, I would strip the whole bunch of them. They're all corrupt. They've all abused their power. They've all betrayed the American people with a political agenda. They tried to steal and influence an election in the United States.

Mr. Trump has threatened to revoke the security clearances from others, too, including Bruce Ohr, who is a career official now at the Department of Justice. According to reports, Ohr's wife worked for Fusion GPS, that is the private research firm that compiled the much publicized dossier on President Trump during the 2016 campaign.

So how does all this look to people who have served in the intelligence community?

For that, we turn to John McLaughlin. He had a three-decade career at the CIA. He served as acting director during the George W. Bush administration.

John McLaughlin, welcome back to the NewsHour.
