INDIANAPOLIS (AP): Indiana Gov. Mike Pence says comments made by presumptive Republican presidential nominee Donald Trump about the Mexican heritage of an Indiana-born judge were “inappropriate.”

The Republican governor rebuked Trump on Tuesday, saying it’s not ever appropriate to question the impartiality of judges based on their ethnic backgrounds.

U.S. District Judge Gonzalo Curiel is overseeing a civil case brought against Trump University. Trump says Curiel cannot be impartial because his parents were born in Mexico and Trump wants to build a wall along the border.

Curiel was born in East Chicago and graduated from Indiana University’s Maurer School of Law in Bloomington.

Pence also says he’s focused on his own re-election bid and doesn’t think he must respond to every development in the presidential race.
