Hillary Clinton denounced Donald Trump for his continued refusal to acknowledge that President Obama was born in the United States.

“He was asked one more time: ‘Where was President Obama born?’ And he still wouldn’t say Hawaii. He still wouldn’t say America,” Clinton said at the Congressional Hispanic Caucus Institute gala dinner in Washington. “This man wants to be our next president? When will he stop this ugliness, this bigotry?”

Clinton’s comments came as Trump refused to say that Obama was born in Hawaii during a new interview with The Washington Post’s Robert Costa, despite his campaign aides’ suggestion that he had abandoned his “birtherism.”

“I’ll answer that question at the right time,” Trump said. “I just don’t want to answer it yet.”

Clinton noted that Trump had launched a “racist” attack against an American judge of Mexican heritage, saying that he was not qualified to preside on a legal case involving Trump’s businesses because of his heritage.

And she criticized him for calling the pastor of a church in Flint, Mich., a “nervous mess” after she asked him not to launch campaign attacks from the pulpit.

“How insulting. How dead wrong,” Clinton remarked.

Clinton added that Trump’s “reset” would never come.

“He’s tried to reset himself and his campaign many times,” Clinton said. “This is the best he can do. This is who he is. And so we need to decide who we are.”
