He did put on a weird stank face when he did it. He thought he was doing something but I don’t think he was aiming for nazi salute. He’s happy to trigger the libs over it but I think in the moment it was somewhere between the weird jump he did on stage and the ketamine putting enough holes in his brain that he thought this was a normal ‘my heart goes out to you all’ gesture.
If it was intentional I don’t think he would choose this venue. Trump has gotta be so pissed at him for stealing the media spotlight and making him look bad.
