Eric Trump, son of the GOP presidential candidate and an executive in The Trump Organization, agrees with his dad: the Republican delegate selection process is "corrupt."

Speaking on Fox News Channel's Fox & Friends Monday morning, Eric Trump echoed his father's recent criticisms of the way the GOP is allocating many of its delegates at conventions, which his main rival, Texas Sen. Ted Cruz, has capitalized on.

"Well, it is a corrupt system, he's 100% right," Trump said, agreeing with his dad.

"I mean, people in the United States they vote, and here you have a little boys club and they decide who they want to be commander in chief," Eric Trump said.

He added: “The Republican Party has, I think, a perception problem.”

Trump continues to lead in the overall delegate count, but has seen his advantage slip somewhat as Cruz has picked up delegates at state conventions, most recently this weekend in Wyoming where the Texas senator added another 14.

The New York billionaire has railed against Cruz's efforts in recent days, tweeting on Sunday that "Lyin' Ted Cruz can't get votes ... so he has to get his delegates from the Republican bosses."

Trump is favored to win Tuesday's New York primary, where 95 GOP delegates are at stake.
