He encouraged his supporters to protest at the capital, perfectly legal. He didn't tell them to invade it. They got carried away and should be punished for any laws they violated.
I think Trump ought to be impeached for lying to his supporters. He said he was going to go down to the Capitol with them. Instead, he took a limo back to the White House to watch the riot on TV. If he had gone down to the Capitol with them like he said he would, he could have stopped them from misunderstanding him when he said they had to fight, and instead the rioters would have just sung
Kumbaya as he intended. The problem is his supporters are all morons, and took what he said literally. Really, don't you think the riot looked a lot like an episode of
Duck Dynasty. Can you see any of those guys down at Mar-A-Lago sipping champagne and eating canapes? They are not exactly polite company, if you know what I mean. Besides, unless they took out one of those free federal student loans, they would never be able to afford the initiation fee.
