Donald Trump said Tuesday night that the political system is "stacked against me," and accused the Republican Party of conspiring to stop him from clinching the party's nomination.

At a special CNN town hall in New York City ahead of next Tuesday's crucial New York primary, Trump said: "I know the rules very well, but I know it's stacked against me by the establishment."

The GOP presidential front-runner blasted "unfair" results in Colorado -- where he was swept by Ted Cruz at a party convention this weekend -- and Louisiana, where he won the primary but Cruz is seeking to sway delegates. Those developments, he said, were the result of establishment Republicans working against his campaign.

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

Trump, saying the Republican Party is "100%" controlled by the Republican National Committee, said he believes the RNC is rooting against him.
