Through a range of witness testimonies, the committee demonstrated that Mr. Trump never reached out to the heads of any law enforcement or national security department or agency in the government to seek help in responding to quell the violence. Fox News footage, which Mr. Trump was watching from his dining room, showed how the Capitol Police were under siege, massively outmanned and struggling to repel the crowd. But the president remained unmoved.

The Chairman of the Joint Chiefs of Staff, Gen. Mark Milley, expressed dismay with Mr. Trump’s response in his interview with the committee. “You’re the commander in chief — you’ve got an assault going on in the Capitol of the United States of America and there’s nothing? No call? Nothing? Zero?” General Milley said in audio of his deposition.
