President Donald Trump today signed a Presidential Memorandum revoking any active security clearance currently held by Chris Krebs, the former director of the Cybersecurity and Infrastructure Security Agency, who famously rumbled publicly with Trump over the latter's false allegations of election fraud during and after the 2020 presidential election. Trump, at the end of his first presidential term, fired Krebs via a November 17 tweet, two weeks after losing his re-election bid to President Joe Biden, saying that Krebs' claims about the security of the election were inaccurate and accusing him of overstepping his authority as a government official.
