Donald Trump says illegal immigration costs $113 billion a year

In his speech in Arizona, Donald Trump outlined all the ways he plans to address illegal immigration if elected to the White House. The United States has to act, he said Aug. 31, because illegal immigration comes at a steep cost.

"Illegal immigration costs our country more than $113 billion a year. And this is what we get," Trump, the Republican presidential nominee, said. "For the money we are going to spend on illegal immigration over the next 10 years, we could provide 1 million at-risk students with a school voucher, which so many people are wanting."
