They should be allowed to visit at any time, with prior authorization just like everyone else. They CAN NOT INTERFERE WITH LAW ENFORCEMENT, PUSH THEIR WAY PAST THEM, OR ASSAULT THEM all in the name of grandstanding to get on the news, and give the impression that they really give a rat's tail.
I have no sympathy for anyone that decides to go to an area just to thwart law enforcement who are there to do their job. People can't seem to understand that these are not Trumps laws but have just been ignored by previous administrations. It's about time that a president finally has the stones to get rid of these lawbreakers.
