Trump said, because of the Russian Federation investigation, revoking Brennan's security clearance was "something that had to be done".
James Clapper, the former director of national intelligence. (The White House press release announcing the revocation was dated July 26, suggesting they've been holding this for awhile.) I don't buy it.
Sen. Chris Van Hollen of Maryland said of Trump, "Leaders behave like this in dictatorships, not democracies".
The move to pull his security clearance prompted immediate outrage, including from Brennan himself.
"Security clearances for those who still have them may be revoked, and those who have already lost their security clearance may not be able to have it reinstated", Mr. Trump said in the statement read out by Ms. Sanders.
"Public officials should not use their security clearances to leverage speaking fees or network talking head fees", Paul tweeted, questioning whether Brennan was "making millions of dollars divulging secrets to the mainstream media with his attacks" on Trump. The president was on an extended working vacation at his New Jersey golf club last week.
Brennan has been extremely critical and outspoken about the president's conduct, for example, calling Trump's performance at a joint press conference last month with Russian President Vladimir Putin in Finland "nothing short of treasonous".
Brennan continued that criticism on Wednesday.
Admiral Michael Rogers, Director of the National Security Agency and commander of U.S. Cyber Command, testifies during a House Armed Services Committee hearing on May 23, 2017. "I never thought I would see it here in the United States".

City opened its Premier League title defence with a 2-0 win at Arsenal on Sunday. "I am privileged to be manager of Manchester City ".
"Clearances are taken away for security violations, usually after an investigation", McLaughlin said.
"More broadly, the issue of Mr. Brennan's security clearance raises larger questions about the practice of former officials maintaining access to our nation's most sensitive secrets long after their time in government has ended", Sanders said.
What needs to be borne in mind in all this is, as former FBI Director James Comey himself has admitted: "I was making decisions in an environment where Hillary Clinton was sure to be the next president". That statement has been backed up by several senior former intelligence officials, as well as the former top lawyer for the director of national intelligence.
Asked if Mr. Trump is targeting his political critics by revoking their security clearances, Ms. Sanders replied in the negative.
So what, who's going to stop him? "I don't know what it is that is behind that, but I think that's why it's critically important that Bob Mueller and his investigators be allowed to continue their work unimpeded by Mr. Trump or anyone else in the administration". His White House has had difficulties with questions of whether Trump has any high-ranking African-Americans in his White House.
Clapper as well as Michael Hayden, the Central Intelligence Agency director under President George W. Bush, accepted analyst positions with CNN and regularly use airtime to criticize Trump.
Of course, if there were any actual wrongdoing in the execution of the Russian Federation investigation, the government could take serious legal action against those people.
"So I guess that's what we all have in common", Clapper said.
The White House has been besieged by a scandal over a former aide's tell-all memoir in recent days and often tries to defuse crises by stoking new controversy.
