Eric Trump: Paul Ryan's Backing Is Not Necessary

Tens of thousands of immigrants are rushing to become U.S. citizens ahead of the presidential election, so they can vote against Donald Trump.

Arizona Sheriff Joe Arpaio, a Trump supporter, said he's not worried, since there's no guarantee that all the immigrants who are newly registered to vote will even go to the polls, let alone unanimously vote Democrat.

Neil Cavuto pointed out that many polls show Trump trailing Hillary Clinton significantly among Hispanic and Latino voters.

Arpaio argued that those numbers will change as they learn more about Trump's policies and how he's the best candidate for jobs and the economy.

"The Hispanic community will fold into the program, too," Arpaio said. "They're here to work, they're here to take care of their families, and they're good people."

On the other hand, he said, illegal immigrants, especially those who commit crimes, must be dealt with. He added that Trump is also the strongest candidate on that issue.

Arpaio said that he hopes Congress doesn't try to force Trump to backtrack on his tough stance on illegal immigration.

"We have to have Donald Trump not give in, to do something about the problem," Arpaio said. "He's our only savior right now."
