There are simply not enough border agents to deal with all of this. 

biden is, AT THIS MOMENT IN TIME, 100 miles away but refuses to visit the chaos at the border because he doesn't want to see the destruction he's caused because he's a jealous old man.  biden thinks these people are better than the actual residents of the USA, whose money he has no problem giving away or spending for ridiculous things. biden needs his ass kicked across the border and he needs to be forced to stay there for an unlimitied, unspecified amount of time until he learns a lesson, which could take a long time since he's quite dense in the head!

That idiot he has for a press secretary is only capable of reading the notes put in front of her, she has no REAL clue what the hell is going on at any point in time or at any place on the map.  She is just plain clueless.  No wonder she has the job biden GAVE her, he couldn't find anyone else stupid enough to take the position and tell those whopper lies!
