"I think that Bruce Ohr is a disgrace, with his wife, Nellie", Trump told reporters outside the White House. "I know that I've gotten tremendous response from having done that, because security clearances are very important to me". "For him to be in the Justice Department and doing what he did, that is a disgrace".
Most recently, Ohr has come under scrutiny for his alleged dealings with the author of the anti-Trump dossier and potentially secret meetings with Glenn Simpson of Fusion GPS.
Mr Ohr's wife, Nellie, worked for Fusion GPS during the campaign - something Mr Trump has tweeted about to highlight his assertions of political bias behind the Russian Federation investigation.
In an op-ed for the New York Times, Brennan renewed his charges that Trump and his aides may have known about and cooperated with Russian attempts to influence the 2016 presidential election. All of them have either sharply criticized Trump or are in the crosshairs of the president's congressional allies as they seek to cast doubt on the special counsel probe led by Robert Mueller III.
Later yesterday, the retired Navy admiral who oversaw the raid that killed Osama bin Laden called Mr Trump's moves "McCarthy-era tactics".
Sanders added that Trump would review the security clearances of other critics: former FBI Director James Comey, former Director of National Intelligence James Clapper, former CIA and NSA Director Michael Hayden, former National Security Advisor Susan Rice, former Deputy FBI Director Andrew McCabe, former FBI Deputy Assistant Director Peter Strzok, and former FBI lawyer Lisa Page; the FBI veterans no longer have clearances per Bureau exit procedures.
The letter alleges that Trump's revoking of Brennan's clearance "has nothing to do with who should and should not hold security clearances - and everything to do with an attempt to stifle free speech". Trump said, nevertheless, that Mueller should be allowed to finish a report on Russia's interference in the 2016 US presidential election.
Brennan, who led the Central Intelligence Agency during most of Obama's second term, has emerged as one of Trump's fiercest critics, denouncing his performance at a summit with Russian President Vladimir Putin last month as "treasonous". Ohr had a role in the investigation into Russia's attacks on the 2016 US elections, which Trump has called a 'rigged witch hunt, ' and Trump has threatened revoking security clearances for numerous highly-positioned officials involved in that investigation.
A group of top former officials who served under both Republican and Democratic administrations called the revocation of Brennan's security clearance "unprecedented". He added, "So I think it's something that had to be done".
On Thursday, Judicial Watch president Tom Fitton tweeted about their lawsuit for documents relating to Brennan's leak to Reid, and said pulling Brennan's security clearance was "the right call".
