All that MIGHT work if you ignore the rest of the speech and only concentrate on a few words he was careful to say, but not when as he was watching the occupation of the U.S. Capitol by people he'd been addressing an hour earlier that Trump did.....NOTHING. We now know people close to him were desperately calling the WH to get Trump to act. When he did he told the world he loved them. He didn't condemn the violence, didn't summon the NG. He did throw Pence under the bus, again, though which is nice, and it was Pence and others by all accounts who did get the military presence there to put down the insurrection, while Trump had his fat ass glued to the TV watching it and loving what he was seeing, while everyone around him is desperately trying to get him to do his duty.
So, no, that excuse fails because of what Trump did during the insurrection. It's also a big clue in my view that those at the top of the GOP and who know all this, McCarthy, McConnell and Cheney among others, are not defending Trump. McConnell for his part says he'll never talk to Trump again and will we're told allow GOP senators to make a conscience vote on impeachment, and hasn't opposed it. Cheney voted to impeach. McCarthy said Trump was responsible. Maybe it's because they were all put at risk and KNOW Trump did nothing to help them.
