Trump responded, “Because you’d be in jail.”

Before that exchange, Trump said he would appoint a special prosecutor to investigate Clinton if he became president.

“If I win, I’m going to instruct my attorney general to get a special prosecutor to look into your situation because there has never been so many lies, so much deception, there has never been anything like it, and we’re going to have a special prosecutor,” Trump said.
