What You Need to Know About the 'Rules' Donald Trump Is Complaining About

Trump has been sparring with the RNC over the delegate acquisition rules.

"They changed the rules a number of months ago," Trump added. "You know why they changed the rules? Because they saw how I was doing and they didn't like it."

He added today: "Nomination process known for a year + beyond. It's the responsibility of the campaigns to understand it. Complaints now? Give us all a break."

The rules in question are the state-level Republican Party rules that determine how each state's delegates are allotted.

Those rules were set on a state-by-state basis, so the terms of the allotments and the dates when they were set differ.

Kyle Kohli, the communications director for the Colorado Republican Party, told ABC News that the group's executive committee finalized their rules in September and that they were made public for all candidates on Oct. 1.

As for general convention rules in July, those have not been set yet: Each convention sets its own rules every four years, so those rules will not be officially adopted until after the Convention Rules Committee, made up of 112 delegates, agrees to a set they develop a week before the convention.
