During the 2021 storming of the United States Capitol, Coons was evacuated from the Senate chambers, along with other Senators and staff. He said there were "some scary and chaotic moments" during the attack. When the Senate reconvened to certify the Electoral College vote count, Coons called for Trump's removal, saying he "poses a real and present threat to the future of our democracy". He called for the invocation of the Twenty-Fifth Amendment to the United States Constitution the day after the event on "Good Morning America". That same day, January 7, he called for Republicans Josh Hawley and Ted Cruz, who both supported the insurrection, to resign from the Senate.
