Is Trump for real on immigration?

It will be one of the big post-debate fact checks, the kind that gets candidates awarded multiple Pinocchios or told their pants are on fire.

At Wednesday night's Republican debate, a moderator started to ask Donald Trump about calling Marco Rubio "Mark Zuckerberg's personal senator" because of the Floridian's support for increasing the number of H-1B visas.

"I was not at all critical of him. I was not at all," Trump shot back. Pressed further, he insisted, "I never said that. I never said that." He told the moderator she got her facts wrong.

It was an effective moment for Trump — "You people write this stuff" — but lo and behold, the comments did really appear on his website. Media outlets wondered if Trump had even read his own immigration policy paper.
