Revoke my security clearance too

William McRaven, commander of the US Navy SEAL raid that killed Osama bin Laden, condemned President Donald Trump on Thursday for revoking the security clearance of former CIA chief John Brennan and asked that his be withdrawn as well.

The decorated retired Navy admiral, in an open letter published in The Washington Post, defended Brennan as "one of the finest public servants I have ever known" and accused Trump of using "McCarthy-era tactics."

"Few Americans have done more to protect this country than John," McRaven said.

"Therefore, I would consider it an honor if you would revoke my security clearance as well, so I can add my name to the list of men and women who have spoken up against your presidency," he said.

McRaven was the head of US Joint Special Operations Command from 2011 to 2014 and supervised the SEAL raid that killed bin Laden in Pakistan in 2011.

Trump revoked the security clearance of Brennan on Wednesday and warned several other prominent critics that they too risk being blacklisted.

Following the president's summit last month with Russia's Vladimir Putin, Brennan -- who headed the CIA under Obama -- described Trump's behavior as "nothing short of treasonous."
