The tweet has been deleted. Van Orden’s office told me he meant to reply to White House Press Secretary Karoline Leavitt's tweet saying "VICTORY!"
It doesn't matter whether it was a mistake or not. Republicans did something abhorrent, and this guy is on their team.
It's extremely telling that even Republicans don't want to be associated with what they've done. So, even they know that they've done something wrong.
If you really believed Republican actions were the best for America, you would be saying "YES!" to that tweet. You'd be bragging about it. But you can't brag about it because you know it's inhumane and evil.
