Donald Trump Jr. could be the one to officially make his father the GOP nominee for president at the party convention in Cleveland.

Donald Jr., 38, is a New York delegate and the state GOP has offered him the role of announcing the New York vote from the convention floor, which could be timed to put his dad “over the top” of the 1,237 delegates needed to clinch the nomination.

State GOP chairman Ed Cox confirmed the ceremonial role has been offered to Donald Jr. and said the plan is being reviewed by the Trump campaign. The convention runs from July 18 to 21.

“We would like to be the delegates to put Donald Trump over the top. We deserve to be the state. It would be an honor,” Cox said.

“We would love to have Donald Jr. do it. It would be wonderful to have a member of the Trump family announce that. The whole room would go wild.”

Cox said he personally discussed the plan with both Donalds.

Trump’s landslide victory in the April 19 New York primary — his home state — put him on the path to the nomination.

The rout came after he lost the Wisconsin primary to Ted Cruz two weeks before.

Two of Trump’s other children, Ivanka and Eric, like Donald Jr., play major roles in their dad’s campaign.

But Ivanka and Eric could not vote for their dad in New York ‘s GOP primary in April because they were not registered Republicans at the time.
