In-state tuition rates, not complete tuition. And only if they qualify academically, I assume. And they wouldn’t all be going to the expensive universities. That bit about how much it would cost for each student was very deceptive.
Border protection is much more important. And he sounded OK on that to me.
My grandchildren,who live in the Northeast,would love to go to the University of Texas at in-state tuition rates.
Guess that’s a no-no though.
