WASHINGTON (AP) — New Jersey Gov. Chris Christie says that Donald Trump has the right to express his opinion and that he’s not a racist.

Christie defended the presumptive Republican nominee who has been criticized for saying U.S. District Judge Gonzalo Curiel cannot judge him fairly because he is of Mexican heritage and Trump plans to build a wall with Mexico.

The former Republican presidential candidate and his son, Andrew, are delegates for Trump. They voted Tuesday at the firehouse in their hometown of Mendham. Their names are on the ballot with Trump’s.

Christie told reporters that he wouldn’t take questions on what he called the “judge kerfuffle.”
