Donald Trump tore into the Commission on Presidential Debates as a "rigged deal" because one of its co-chairmen, Mike McCurry, was White House press secretary during former President Bill Clinton's administration.

The GOP nominee told a rally Wednesday in Ocala, Fla. that he "just found... out" McCurry's role on the panel.

The other co-chairman is Frank Fahrenkopf, a former Republican National Committee chairman.

"By the way, you know that so-called Commission on Presidential Debates?" Trump asked his audience, Politico reports.

"The head guy used to work for Bill Clinton. Did you know that? I just found that out. The head guy worked for Bill Clinton.

"Ay, ay, ay, what a rigged deal this is."

"I have no respect for that group, by the way, I have none," he added. "It sounds good — presidential commission. Give me a break."

"That's why I was so happy what we did to annihilate the enemy the other day," he said, referring to the second presidential debate Sunday in St. Louis, Mo. "So happy. Because we're dealing against a very dishonest system."

The Hill noted the commission started in 1987 as a nonpartisan organization and was headed by the two major parties' chairmen, Fahrenkopf and Paul Kirk.

Trump railed against the commission after the first debate, when he had trouble with his audio levels with "the really bad microphone," asking in a tweet, "So why didn't they fix it?"
