Democratic presidential candidate Hillary Clinton brushed off critiques made by Republican presidential candidate Donald Trump in an interview aired Sunday.

Clinton was asked on ABC News’ “This Week” to respond to Trump calling her “crooked Hillary.” She replied that she doesn’t respond to Trump’s “string of insults” and that she looks forward to running against him if they are their respective parties’ nominees.

“What I’m concerned about is how he goes after everybody else. He goes after women. He goes after Muslims. He goes after immigrants. He goes after people with disabilities. He is hurting our unity at home,” Clinton said. “He is undermining the values that we stand for in New York and across America. And he’s hurting us around the world. He can say whatever he want to say about me. I really could care less.”
