Former CIA Director John Brennan risked damaging the intelligence community with his anti-Trump comments, retired Adm. Michael Mullen, former chairman of the Joint Chiefs of Staff, told "Fox News Sunday."
However, Mullen added, Trump's decision to revoke Brennan's security clearance last week raised significant concerns.
The White House announced Wednesday that President Trump had revoked Brennan's security clearance, in the first decision to come from a review of access for several top Obama-era intelligence and law enforcement officials.
Specifically, the president's statement criticized Brennan for falsely telling Congress that the CIA had not infiltrated Senate computers, and for claiming that the unverified Steele dossier was not a factor in 2016 intelligence assessments.
Also speaking to "Fox News Sunday," Senate Homeland Security Committee chairman Ron Johnson, R-Wis., criticized Brennan's political comments, but suggested an alternative to yanking his clearance.
Has anyone looked at the mistakes that John Brennan made while serving as CIA Director? He will go down as easily the WORST in history & since getting out, he has become nothing less than a loudmouth, partisan, political hack who cannot be trusted with the secrets to our country!— Donald J.
