From Philip Bump at the Washington Post:

The first came shortly after Pence was evacuated from the Senate chamber following rioters having gained access to the building. The vice president was hustled into a ceremonial office across a short hallway, just moments before a crowd of rioters climbed a set of stairs to arrive near the same spot. Had Officer Eugene Goodman not had the presence of mind to goad the rioters in the opposite direction, they would have passed down the hallway and past the door of the room in which Pence was sheltering.

We knew about that brush with danger. During the hearing on Thursday of the House select committee investigating the riot, we learned about the second — one that came after Donald Trump had specifically targeted his vice president with tweeted words of condemnation….

Around 2:25 p.m., the video stated, Pence was evacuated from the ceremonial office down some stairs to a more secure location. In an animation, the committee showed how close the rioters were as that evacuation was taking place: 40 feet.

This is important information for several reasons.

One is that it reinforces that the danger to Pence was ongoing. Rep. Pete Aguilar (D-Calif.) revealed in the hearing that “a confidential informant from the Proud Boys told the FBI the Proud Boys would have killed Mike Pence if given a chance.” Given that members of the Proud Boys were both among the earliest arrivals inside the building and had a demonstrated predilection for violence, that’s not an idle threat.

Another is that it reveals that Pence was in peril even after Trump’s tweet.

The crowd was already furious at Pence; Trump’s tweet seemed like “pouring gasoline on the fire,” as one former White House aide said in recorded testimony. That’s because the staff — and, almost certainly, Trump — knew about the violence that was already underway at the Capitol, another significant revelation that emerged from the hearing.
