I think it is the riot thingy, but you can bet the Left will make the comparison and claim it is the ONLY reason.
This says nothing. I wouldn’t worry about this. If there are riots in DC, its harder to secure the hotel and surrounding area than the Whitehouse. GWB was at the White House in 2004. Again, This says nothing but security. That being said, when I first read this, I though the party was going to be in Florida, but that’s not the case. It makes no sense to have it at the hotel in DC. The streets could be crazy.
