The Senate Intelligence Committee’s top Democrat, Sen. Mark Warner of Virginia, plans to introduce a resolution that would prevent the President from arbitrarily revoking security clearances, days after President Donald Trump revoked the security clearance of former CIA Director John Brennan.

“I will be introducing an amendment next week to block the President from punishing and intimidating his critics by arbitrarily revoking security clearances. Stay tuned,” Warner tweeted Friday.

The amendment would be unlikely to pass but is expected to draw heavy Democratic support as they call attention to the controversy surrounding Trump’s revoking of Brennan’s clearance, a move which was announced Wednesday.
