Retired Adm. William McRaven, the man who oversaw the 2011 Navy SEAL raid that killed Osama bin Laden, issued a stunning rebuke of President Donald Trump’s decision to revoke the security clearance of former CIA Director John Brennan on Thursday, defending the former spy chief as “one of the finest public servants I have ever known.”

In an op-ed published by the Washington Post, McRaven, a former Navy SEAL who led US Joint Special Operations Command from 2011 to 2014, not only called Brennan “a man of unparalleled integrity,” but volunteered to have his own security clearance revoked in an act of solidarity.

“Few Americans have done more to protect this country than John. He is a man of unparalleled integrity, whose honesty and character have never been in question, except by those who don’t know him,” McRaven wrote.

“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 added.

His comments come just one day after Trump announced his decision to revoke Brennan’s security clearance, marking an unprecedented use of a president’s authority over the classification system to strike back at one of his prominent critics.

“This action is part of a broader effort by Mr. Trump to suppress freedom of speech & punish critics. It should gravely worry all Americans, including intelligence professionals, about the cost of speaking out. My principles are worth far more than clearances. I will not relent,” Brennan tweeted after the announcement.

McRaven, who resigned as chancellor of the University of Texas in Austin earlier this year, is widely respected among the tens of thousands of active and retired special operators and his message will likely resonate within that community.

“Through your actions, you have embarrassed us in the eyes of our children, humiliated us on the world stage and, worst of all, divided us as a nation,” McRaven said of Trump.

“If you think for a moment that your McCarthy-era tactics will suppress the voices of criticism, you are sadly mistaken. The criticism will continue until you become the leader we prayed you would be,” he added.
