10 billion for Mexico, 10 coming back to crooked US Politicians.

Yep,
Gotta be the money. Money talks, just talk walks.

So he sent 20 billion of OUR tax dollars to Mexico?  Isn't that nice...

My guess is Biden gave them the money and told them from now on you need to bring the illegals into the US on planes. And of course the cartels will get their cut of it as they always do.

Then lying Biden will try to convince Americans that on-the-ground border crossings are way down because his new immigration bill policies are working.

Yep,
It is a Presidential election year. Got to make Biden look good in the eyes of voters with short memories.
