The Republican president said in a statement on Wednesday that he revoked Brennan's authorization for making what he called "unfounded and outrageous allegations" about his administration and was evaluating whether to strip clearances from other former top officials.
Trump on Wednesday announced that he was revoking Brennan's security clearance as a result of national security concerns, though the move was widely viewed as an effort by the president to silence one of his most fervent critics.
"I call it the rigged witch hunt, [it] is a sham, Trump was quoted as saying "and these people led it!" And these people led it. Trump said he is reviewing security clearances for the eight individuals pictured.
William McRaven, a retired Navy admiral who served as commander of the U.S. Joint Special Operations Command from 2011 to 2014, wrote an opinion piece for The Washington Post Thursday asking President Trump to revoke his security clearance in solidarity with former Central Intelligence Agency director James Brennan, who had his security clearance revoked Wednesday.
Brennan, whose criticisms of Trump have escalated in recent months, wrote that the president was "desperate" to end the Russian Federation investigation.
While Trump has repeatedly insisted there was "no collusion", Brennan wrote that the "only questions that remain are whether the collusion that took place constituted criminally liable conspiracy, whether obstruction of justice occurred to cover up any collusion or conspiracy, and how many members of "Trump Incorporated" attempted to defraud the government by laundering and concealing the movement of money into their pockets". Trump said in an interview published Wednesday that the Russian Federation investigation factored into his decision regarding Brennan. And California's Adam Schiff, the ranking Democrat on the House intelligence committee, tweeted, "An enemies list is ugly, undemocratic and un-American".
Shortly after they sent out the first statement, the White House released a second, identical statement that was undated.
Sen. Chris Van Hollen of Maryland says of Trump, "Leaders behave like this in dictatorships, not democracies".
"By issuing such a statement, Mr Trump was not only encouraging a foreign nation to collect intelligence against a United States citizen, but also openly authorising his followers to work with our primary global adversary against his political opponent", Brennan wrote.
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. Sanders is citing Brennan's "erratic conduct and behavior" and accusing him of "lying" and "wild outbursts".
In the Journal interview, Trump said he was prepared to yank Brennan's clearance last week, but that it was too "hectic".
