Hillary Clinton said Wednesday that at this point in the race all Donald Trump’s campaign has left is “negativity.”

In a speech at a voter registration event in Pueblo, Colorado, Clinton slammed the Trump campaign’s “scorched-earth” tactics as a last resort.

“All they have left is negativity,” she said. “And we’re not going to let him get away with it.”

During the second presidential debate on Sunday, Trump attacked Clinton in particularly personal terms. Before either candidate took the stage, Trump held an impromptu press conference with three women who have accused Bill Clinton of sexual misconduct, and a fourth who was the victim in a rape case where Hillary Clinton was appointed the public defender for the accused. During the debate itself, Trump took things further by telling Clinton that she should be “ashamed” of her past actions, calling her “the devil,” and telling her that she would be “in jail” if he was elected president.

Clinton went on to talk about the groups that Trump has insulted on the campaign trail, citing comments made by the mother of a child adopted from Ethiopia to illustrate the effects of Trump’s comments.

“This little boy named Felix is now 10 years old. He’s only lived in the United States, and his mother wrote me and she said, after hearing Donald Trump, he turned to her and he said, ‘Mommy, will he send me back to Ethiopia?'” Clinton recounted. “That’s the kind of fear and anxiety that I hear from immigrant families who are scared to death.”

Clinton asked supporters to reassure children: “In this election we will demonstrate that America is better than what Donald Trump says and represents.”
