Donald Trump is not looking forward to having Anderson Cooper moderate his second presidential debate against Hillary Clinton because he doesn't think the CNN anchor "can be fair."

"I don't think Anderson Cooper should be a moderator, because Anderson Cooper works for CNN and over the last couple of days, I've seen how Anderson Cooper behaves," the Republican presidential hopeful told the Washington Post in an interview published Thursday.

Trump hasn't appeared on CNN for months and frequently criticizes the network for lending too much favorable coverage to his Democratic opponent. "CNN is the Clinton News Network and Anderson Cooper, I don't think he can be fair," he told the Post.

"He'll be very biased, very biased," Trump continued. "I don't think he should be a moderator. I'll participate, but I don't think he should be a moderator."

Cooper and ABC News' Martha Raddatz will moderate the second debate between Clinton and Trump in the format of a town hall in St. Louis, Mo., on Oct. 9. The first debate between the two major party nominees will take place on Sept. 26 at Hofstra University in New York.
