I'll ask again; what do you expect her to do at the border, look around, take photos, interfere with the folks trying to deal with the crisis, by taking large numbers away from their patrols to attend the VP? I know trump didn't give a flying #$%^ about that, since he craves such attention, but honorable people will NOT.
She and Biden and the left think that by not looking at the border, not seeing what is going on there and not being seen seeing what is going on there, that they can avoid responsibility for what is going on there. And it is, a hidden fact, that they, Biden in particular, are directly responsible for the disaster going on there.
As for trump, he enforced our immigration laws and that kept the hoards from trying to get in via the cartels. Since Biden undid Trumps border policy, the cartels have taken up shop at the border; human trafficking up 30 fold, drug smuggling into the US up by even more. The human rights abuses are horrid even by cartel standards.
So don't tell us Trump didn't care. He enforced the law. It worked. Biden undid that.
