Donald Trump referred to Hillary Clinton as “the devil” during the presidential debate on Sunday night.

Accusing the Democratic nominee of stealing the primary from Bernie Sanders, Trump said, “I was surprised to see him sign up with the devil.”

Trump also alleged Clinton lied throughout her campaign, focusing on her use of a private email server. He called on Clinton to apologize for deleting her emails and threatened to prosecute her if he won the election.

“There has never been so many lies, so much deceit,” he said. “So we’re going to get a special prosecutor and we’re going to look into it.”

He later said Clinton would “be in jail” if he were President.
