IIRC, he was in the US on a student visa. Then he dropped out and started working. Wouldn't that mean his visa would be voided, and he then become gasp and illegal immigrant?
I mean the headline is true, but if ores the fact that Elon and his brother were literally talking about this during an interview the day before. Biden is just repeating what Ellon himself admitted.
I don't think it's purpose is to highlight the usefulness of illegel immigrants, but to stop him in his tracks lambasting about illegal immigrants all day. It weakens their main argument they have. What is left over when they don't have that is "Drill baby drill" and "Kamala is dumb".
