The editorial follows reports that the president relayed highly classified information to Russian Foreign Minister Sergey Lavrov and Ambassador Sergey Kislyak in a recent Oval Office meeting, as well as reports of a memo drafted by former FBI Director James Comey that allegedly claims Trump asked him to end the FBI probe into former national security adviser Michael Flynn.

“The portrait of an inexperienced, impulsive chief who might spill secrets to an overseas foe is one to which Mr. Trump has too often contributed,” the piece said.

The editorial board went on to call the incidents “political mismanagement" on the part of Trump.

“Mr. Trump’s strife and insults with the intelligence community were also bound to invite blowback,” it said.

The editorial board concluded with a warning to Trump that congressional Republicans will drift away from supporting the president if “he looks like a liability.”

“Millions of Americans recognized Mr. Trump’s flaws but decided he was a risk worth taking,” the board said. “They assumed, or at least hoped, that he’d rise to the occasion and the demands of the job. If he cannot, he’ll betray their hopes as his presidency sinks before his eyes."
