Have illegal border crossings increased since our new president seized power?

There are more migrants seeking entry because of Latin America problems. They are amassed at the border right now. Biden told them to "wait". So that implies they will be let in later. Meanwhile Biden set new rules for arresting illegals. 

What happened to traitor trump's giant $50,000,000,000 fence?

Yes and even people who have been deported are not supposed to be stopped.  Everybody is supposed to be allowed in.  Those drug cartels must be in heaven but ready to murder more people in the US sanctuary cities.  Sanctuaries for anyone BUT American citizens.  Of course, some of the murdered people also ran across the Southern border.  Its a horrible situation.

That which is ASSerted without evidence IS dismissed without evidence.

Yes. Since he was elected, border crossings have increased. And it is "Mark Dannels". I used to work on his vehicle years back. 

Riiiiight and you have no credible citation because?

Aren't you tired of rehashing this illegal immigrant boogeyman every time you lose an election.
