Donald Trump said he thinks a Muslim judge could treat him unfairly due to his proposed ban on Muslims entering the U.S.
"If it were a Muslim judge, would you also feel like they wouldn't be able to treat you fairly because of that policy of yours?" moderator John Dickerson asked the presumptive Republican presidential nominee.
"It's possible. Yes, that would be possible. Absolutely," Trump responded. "I'm not talking about judging. I'm talking about common sense."
Trump was being asked about his recent comments about U.S. District Judge Gonzalo Curiel. Curiel is presiding over two of his Trump University lawsuits. Trump called the judge "hostile" and said he believed he is "Mexican." Curiel was born in Indiana and is of Mexican descent.
"I have a judge who is a hater of Donald Trump," he said during a rally last month.
A day after saying he would vote for Trump, House Speaker Paul Ryan said he disagreed with Trump's comments.
Democratic presidential front-runner Hillary Clinton has also called out Trump's statements in recent days, calling them "terrible" and "outrageous."
"He is temperamentally unfit to be president," she said during a campaign stop in California on Friday.
Trump doubled down on his comments Friday, saying Curiel should recuse himself.
"This judge is of Mexican heritage. I'm building a wall," he told CNN's Jake Tapper.
Former Attorney General Alberto Gonzales has said Trump is entitled to question whether the judge is fair but said Curiel's "Mexican heritage alone would not be enough to raise a question of bias."
