Mr. Trump cited Mr. Brennan as among those he held responsible for the investigation ...
On Wednesday, Sarah Huckabee Sanders announced that the White House has made a decision to revoke former CIA Director John Brennan's security clearance.
The only question remaining is whether the collusion amounts to a "constituted criminally liable conspiracy", Brennan wrote. McRaven oversaw the operation under President Obama that resulted in the Navy Seals killing bin Laden in 2011.
In an op-ed for the New York Times, Brennan argued the decision to strip his security clearance and review others' is created to muzzle the president's political opponents.
McRaven echoed those sentiments, arguing in his op-ed that Trump has "embarrassed us in the eyes of our children, humiliated us on the world stage and, worst of all, divided us as a nation".
Republicans have so far expressed no criticism of Trump for revoking Brennan's security clearance.
Trump, in an interview with The Wall Street Journal, said he believes Brennan is one of the people responsible for special counsel Robert Mueller's ongoing 15-month probe into links between Trump's campaign and Russian Federation and whether Trump, as president, obstructed justice by trying to thwart the investigation.
He added: "So I think it's something that had to be done". It marked the latest example of the president contradicting a story his aides had put forward to explain his motivations.
All are critics of the president or are people whom Trump appears to believe are against him.
The former Central Intelligence Agency director took aim at Trump for his public call as a candidate in July 2016 for Russian Federation to help find missing emails of his Democratic opponent, Hillary Clinton, who was being scrutinised for having used a private email server while secretary of state.
Sen. Bob Corker, R-Tenn., who chairs the Foreign Relations Committee, said he was bothered by the president's move.
Renato Mariotti, a former federal prosecutor agreed.
"He's acted like a political hack, and not a national security professional", Kennedy said. "Former CIA director John Brennan, whose security clearance you revoked on Wednesday, is one of the finest public servants I have ever known", McRaven wrote.
Brennan described the decision to revoke his clearance as "politically motivated" and "an attempt to scare into silence others who might dare to challenge him". The White House later issued a revised statement with that date removed.
"Like most Americans, I had hoped that when you became president, you would rise to the occasion and become the leader this great nation needs", McRaven said.
