Hillary Clinton said Sunday that she is not worried about Donald Trump's new nickname for her — "Crooked Hillary."

Trump used the moniker Saturday in New York, hoping to replicate what he considers his successful previous nicknames for rivals, "Little Marco" and "Lyin' Ted."

"I don't respond to Donald Trump and his string of insults," Clinton said on "This Week."

"What I'm concerned about is how he goes after everybody else," Clinton continued. "He goes after women. He goes after Muslims. He goes after immigrants. He goes after people with disabilities," Clinton said.

"He is hurting our unity at home. He is undermining the values we stand for in New York," Clinton said of Trump, her fellow New Yorker, days before voters in the Empire State go to the polls for primaries held by both parties.

"He can say whatever he wants to say about me," Clinton said. "I really could care less."
