Trump has been threatening to do it for years, and now the RNC has withdrawn from the Commission on Presidential Debates while crying about fairness.
The Commission on Presidential Debates said that they would be making changes to bring order to the debates, also known as reining in Trump.
"What is a big fact, what is a little fact?...I don't think it's a good idea to get the moderator into essentially serving as the Encyclopaedia Britannica"
"As usual, Hillary & the Dems are trying to rig the debates so 2 are up against major NFL games. Same as last time w/ Bernie. Unacceptable!"
