In the most heated exchange thus far tonight, Marco Rubio hit Donald Trump for his use of illegal immigrant labor. “If he builds the wall the way he built the Trump Towers, he’ll be using illegal immigrant labor to do it,” Rubio charged.

“Such a cute sound bite,” Trump sarcastically replied.


Rubio then hit Trump for outsourcing his fashion line to Mexico and China. “You’ll be starting a trade war against your own clothes and suits!”

“You don’t know a thing about business!” Trump shot back.

“I don’t know anything about bankrupting companies,” Rubio replied to applause. ”I don’t know anything about starting a fake university.”
