NEW YORK (AP/NBC News) – When Donald Trump and Hillary Clinton meet for their three scheduled debates, Trump believes there should be no moderator.

He tells CNBC that he’s afraid he won’t be treated fairly. Trump says he and Clinton should “sit there and just debate.”

Trump said debate moderators will try to be extra tough, because of the criticism that NBC’s Matt Lauer was too “easy on me,” during the network’s Commander-In-Chief Forum last week.

“Well, [Lauer] wasn’t. I thought he was very professional. I have to be honest, I think he’s been treated very unfairly,” Trump added, in reference to the NBC forum, during which the candidates were interviewed separately on stage one right after the other.

Trump says that with a moderator, “the system is being rigged” against him.

The first of three presidential debates will be moderated by NBC’s Lester Holt on Sept. 26 at Hofstra University in Hempstead, New York. The two other debates will be held next month in St. Louis on Oct. 9 and Las Vegas on Oct. 19.
