Of all of the not quite true statements Biden has said, he chooses to correct this one. So saying illegal immigrants is wrong when they are undocumented. POTUS says so.

Undocumented is not illegal when entering the United States..
So what's all this green card shit? Visa's, which are documents, not illegal if you don't have them so why bother?
Joan never apologised for getting the poor girl's name wrong, apologised instead for using "illegal" instead of "undocumented". Why exactly? Why was this so important, this verbal boo boo, that for once he corrects himself straight away for calling undocumented ie unvetted "new comers" illegal? Why not apologise to the girl's family for fucking up her name instead?

Illegals cannot vote. Undocumented? Well, who is against using voter ID when voting? That is why it was important for Biden to set the record straight. The State of the Union.
