You just can't help with the racism, can you?
What was legal about what happened at the southern border? Asylum claims must come at the first country of departure. Let's say you leave Panama and come to Costa Rica. That's where you apply for asylum. But if you fly from Panama to the US you can apply in the US.
What was really happening at the US is that the Biden admin invented procedures that don't exist to do things that aren't legal. As a result, we know that thousands (if not millions) of illegal aliens received SSNs, registered to vote and voted. We know millions used Medicaid, SCHIP and housing resources that were for American citizens, and we know thousands of them broke multiple federal laws even after admission (to include, but not limited to: rape, murder, trafficking, and selling drugs).
So, I'll ask again, what was legal about what happened at the southern border?
