Several ex-intel officers criticized Trump. Now he may revoke their security clearances.

The intelligence officials include John Brennan, James Clapper, and Michael Hayden.

President Donald Trump may revoke the security clearances of former CIA Director John Brennan and several other former intelligence and national security officials.

At a press conference on Monday, White House press secretary Sarah Sanders told reporters that in addition to Brennan, the president is considering revoking clearances for former FBI Director James Comey, former Director of National Intelligence James Clapper, former CIA Director and NSA Director Michael Hayden, former National Security Adviser Susan Rice, and former Deputy FBI Director Andrew McCabe.

Sanders claimed the six former intelligence officials have “politicized and in some cases monetized their public service,” adding that “making baseless accusations of an improper relationship with Russia is inappropriate.” She did not say when the administration would make a decision.

The officials Sanders listed have all criticized Trump and his administration or come under fire from Trump in the past.

After Trump sided with Russian President Vladimir Putin last week at a press conference in Helsinki when Putin said that Russia didn’t interfere in the 2016 US election, Brennan responded by tweeting that it was “nothing short of treasonous”:

Comey has also been highly critical of Trump after the president fired him last year. In an interview with ABC News in April, the ex-FBI chief said Trump was “morally unfit to be president.”

However, it seems like Sanders may have misspoken, or the White House failed to check beforehand: Comey and McCabe have apparently already had their security clearances revoked.

“Andrew’s security clearance was deactivated when he was terminated, according to what we were told was FBI policy. You would think the White House would check with the FBI before trying to throw shiny objects to the press corps,” McCabe’s spokesperson, Melissa Schwartz, said in a statement.

The New York Times also reports that Comey has had no security clearance for about a year, according to a person briefed on the matter.

In an email, Hayden told Vox, “I dont [sic] go back for classified briefings. Won’t have any effect on what I say or write.”

Clapper also responded to Sanders’s claims on CNN, saying that “this is just a very, very petty — a petty thing to do. And that’s about all I’ll say about it.”

After the news, people tweeted about the value of security clearances and what such a move could actually mean.

Earlier on Monday, Sen. Rand Paul (R-KY) said he was meeting with Trump to request that Brennan’s security clearance be revoked. The former CIA director now works as a national security and intelligence analyst for NBC News and MSNBC.

When a reporter asked whether the Trump administration was considering revoking the security clearances of former President Barack Obama or former Vice President Joe Biden, Sanders said she was “not aware” of any plans to do so.
