On this week’s broadcast of “Fox News Sunday,” former Speaker of the House Newt Gingrich said Republican presidential nominee Donald Trump raising concerns in the Trump University case over U.S. District Court Judge Gonzalo Curiel’s Mexican heritage was “one of the worst mistakes Trump has made.”

Gingrich said “This is one of the worst mistakes Trump has made. I think it’s inexcusable. He has every right to criticize a judge and has every right to say certain decisions aren’t right.”

He added, “First of all this judge was born in Indiana. He is an American. Period. When you come to America, you get to become an American and Trump who has grandparents who came to the U.S. should understand this as much as anybody.”
