President Donald Trump revoked the security clearances of
former CISA Director Chris Krebs and former DHS official Miles Taylor, while
ordering investigations into their work during his first term.
As part of a series of executive orders and directives
signed in the Oval Office, Trump issued a Presidential Memorandum on Krebs,
stating that it "addresses his access to existing government
clearances."
White House Staff Secretary Will Scharf explained that the
memo instructs the Department of Justice (DOJ) and "other aspects" of
the federal government "to investigate some of the malign acts" in
which Krebs may have participated while serving as CISA Director.
