  And based on your reporting, how much did the Trump White House know? In particular, how much did the White House chief of staff at the time, Mark Meadows, how much did he know? And why is it problematic to have the chief of staff involved in a rally that was about supporting the president?

• Hunter Walker:

  There's supposed to be a bright line between the White House staff and the political operation.

  And this would certainly be a violation of that. But, of course, that was a pretty regular occurrence during the Trump years. But I think the key thing here is that, A, the highest-level people in the White House were allegedly in contact with these organizers, but, also, they frame Mark Meadows as someone who had an opportunity to tone this down and stop the violence.

  But I think the key thing here is that Trump himself was the major player. They framed the moment that the president said, let's march to the Capitol, sort of encouraged the crowd to march, as a key turning point, where this went from the planned airing of objections to a charge toward the Capitol Dome.
