Chuck Hagel: “This is so unpredictable. And we've never seen anything quite like this in our lifetime, so there is no playbook here.”

The facts speak for themselves, and especially when you look at the many of the witnesses, who are Trump cabinet members, White House officials in the Trump administration, supporters of Mr. Trump.

They're not trained for law enforcement.

I think the GOP is in a lot of trouble. And I do think an encouraging sign, I think the strong control that Mr. Trump has exercised over the Republican Party is dwindling.

It just feeds into all that instability, and unrest, and unpredictability, which makes a damn dangerous world.
