Donald Trump joked Monday night that he may charge CNN for appearing in the next GOP primary debate, but probably won't because he'd be called a "chicken."

Trump bragged to about 5,000 backers at a rally in Georgia that he has been a ratings boon for networks hosting the presidential forums.

But Trump had a suggestion for the upcoming debate.

He would demand that CNN pay $5 million for him to appear in the next debate, scheduled for Dec. 15 in Las Vegas.

Trump said he would give the money to programs that help veterans.
