You do know that a large percentage of the immigrants came to America legally on worker's permits, they just never reapplied and not all of them came from Mexico...like Melania Trump.
Idiot.
I'm bleeding from a ten inch gash across my femoral artery, so I'll worry about this splinter in my thumb first.
No, doofus, you close the bleeding wound and then turn your attention to the other minor cuts and scrapes in order to heal the body.
Since you still probably don't understand, the flood of illegals from Mexico must be stopped so we can -- as a nation -- focus on solving other immigration issues.
Why are you worried about Melania anyway? You didn't have any problems with the Kenyan immigration of the former fraud-in-chief.
