Edward Markey actually said...

"Absent a nuclear attack upon the United States or our allies, no one human being should have the power to unilaterally unleash the most destructive forces ever devised by humankind."

"the President's bombastic words could turn into nuclear reality."

"the President would have that authority under Article II to defend the country."

"there is, in your opinion, a constitutional responsibility for Members of Congress to have to have voted on that before such a nuclear war is commenced by the United States."
