A dozen former intelligence officers condemned President Trump’s “ill-considered and unprecedented remarks and actions” after he revoked the security clearance of former CIA Director John Brennan, and said security clearance decisions should be founded on national security instead of “political views.”

The group of former officers — including former Director of Central Intelligence Robert Gates, former CIA Director Michael Hayden, and former Director of National Intelligence James Clapper — said the White House’s move was politicizing these clearances.
