Any mayor?
Since when do effing “mayors” get to dictate border security policies? The national border is totally under federal jurisdiction. Any mayor arrogantly stupid enough to make an attempt at obstructing of national security will not be mayor much longer - one way or the other. BTW, Sheriffs are the highest elected county official, meaning their say trumps that of some pipsqueak, leftist used-asswipe of a mayor.
The recalcitrant mayors should be arrested for treason.
