"That man (Curiel) is an American, born in the U.S., a judge who has earned that position. I don’t think it reflects well in the Republican Party. I don’t think it reflects well on us as a nation," Rubio said.
Trump has said his comments about the judge came after questions from reporters and others about lawsuits against Trump University. Curiel is the judge overseeing the lawsuits.
Curiel has not publicly responded.
"I ran for president and I warned this was going to happen," Rubio said in regard to Trump’s remarks.
