I Alone Can Fix It: Donald J. Trump’s Catastrophic Final Year by Carol Leonnig and Philip Rucker:
Outside the Capitol, the pro-Trump protest was quickly morphing into a battle scene. Demonstrators so outnumbered law enforcement that hundreds of Capitol Police officers on the western front of the complex had no chance of holding the crowds away from the grounds. They retreated to create a tighter blockade around the Capitol’s grand external balconies and steps, all with the goal of keeping people away from the immediate building. This was no ordinary political protest. It was a riot. Many of those crashing through the outer barricades were wearing military gear, carrying Trump flags, and some were wielding pipes, batons, and cans of bear spray as weapons. A few had climbing gear, and some even brought night goggles and fire-retardant gloves. Some engaged in hand-to-hand combat with the police officers, who chose not to fire on the crowd for fear of triggering gruesome violence.
By 12: 58, Sund knew his officers were getting slammed and they wouldn’t be able to stop the onslaught shoving its way toward the halls of Congress. He needed to declare an emergency and call in reinforcements. He called the House Sergeant at Arms, Paul Irving, requesting he and the Senate Sergeant at Arms, Michael Stenger, approve the emergency declaration and call in the National Guard immediately. Irving said he would get back to him after “running it up the chain,” presumably getting approval from Pelosi and Mitch McConnell.
