“This could turn into a huge relief, or disaster. I don’t like this move. The left is PISSED OFF.”
Hence why I say this: as a security measure the Secret Service needs to have the Governor, the Mayor, and any/all other Leftists who may pose a threat to POTUS arrested/detained/locked up for the entire duration of the POTUS visit. Have Secret Service identify, stop, and contain any suspicious out-of-towners and inspect (using drug/explosive detecting dogs/robots) ALL vans and trucks that could carry weapons or explosives.
We have enough federal assets to follow all of them.
