Mr Brennan, who was director of the Central Intelligence Agency under former president Barack Obama, has been a sharp critic of Mr Trump, frequently appearing on cable television news shows to attack his foreign policy positions.
Trump's action Wednesday in stripping Brennan of his security clearance demeaned "one of the finest public servants I have ever known", McRaven wrote.
Mr Brennan sought to reassure his "Irish brothers and sisters" that the United States is a strong country, but at the moment President Trump is "not upholding the image and reputation of what it means to be an American president. we're gonna get there but we have some rough waters to navigate", he said. Trump said hours after Brennan's clearance was being revoked.
The only question remaining is whether the collusion amounts to a "constituted criminally liable conspiracy", Brennan wrote.
Even by the standards of angry Trump-era criticism, Brennan's words represent an unprecedented attack by America's normally hush-hush spooks on a political leader.

Johnson's lawsuit is the first trial case alleging glyphosate herbicides in weed killers might cause cancer. His was the first case filed by a cancer patient against the agribusiness giant to reach trial.
"So I think it's something that had to be done", he added.
Brennan, a persistent critic of Trump, lashed out at the president for calling former White House aide Omarosa Manigault Newman a "dog" in a tweet, saying "it's astounding how often you fail to live up to minimum standards of decency, civility & probity".
On his Twitter account, Trump reposted several comments supporting his revocation of Brennan's clearance, including one from Sean Hannity, a conservative Fox News television host. Legal experts said the dispute may add to the evidence being reviewed by special counsel Robert Mueller.
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.
Shortly after they sent out the first statement, the White House released a second, identical statement that was undated.

He missed four months at the start of the year when a partially torn tendon in his left wrist, causing him to sit out the Masters. He finished the tournament at 14-under 267 and was two back of Brooks Koepka's lead when he finished the round.
"You look at any of them and you see the things they've done", Trump told the Journal. "The Hillary Clinton whole investigation was a total sham".
There was no reference to the Russian Federation probe in a White House statement Wednesday that was read at a press briefing and then sent out to reporters. "I think that they're very duplicitous".
Trump later changed again, tweeting that he "never fired James Comey because of Russian Federation!"
That directly contradicted a July 2017 statement from Trump Jr. - written with the consultation of the White House - that claimed the meeting had been primarily about adoption.
