According to a report by Reuters, on Wednesday, US President Donald Trump revoked the security clearance of Obama-era CIA Director John Brennan for what he said was a 'series of unfounded and outrageous allegations' as well as sowing 'division and chaos.' In a statement read to reporters by White House spokeswoman Sarah Sanders, Trump announced that he was evaluating whether a series of other former high-ranking officials should also have their security clearances withdrawn, as well.
