Two Republican Party elders on Sunday denounced Donald Trump’s attacks on a Hispanic federal judge, adding to a wave of criticism from party figures of their presumptive presidential nominee.

Over the past week, Trump has repeatedly said that U.S. District Judge Gonzalo Curiel, the Indiana-born jurist presiding over civil fraud litigation in California involving Trump University, is unfit to hear the case because he is of Mexican ancestry and Trump has vowed to build a wall along the U.S.-Mexico border.
