Donald Trump is planning a campaign rally this week in Bethpage — his first on Long Island.

The Republican presidential candidate has requested a permit to hold the rally at 6 p.m. Wednesday at Grumman Studios, Nassau County spokesman Brian Nevin said Saturday night.

County Executive Edward Mangano, a Republican from Bethpage, has not endorsed a candidate for president, but plans to attend the Trump rally, Nevin said.

Nassau Republican Party chairman Joseph Mondello endorsed Trump last month, but county GOP officials said Saturday they had no planned events with Trump’s campaign.

“Mr. Trump was very happy Mr. Mondello endorsed him,” Nassau GOP spokesman Michael Watt said.

The Republican front-runner is seeking to woo Long Islanders before New York’s April 19 presidential primary. He follows rival John Kasich, who is holding rallies Monday in Huntington and at Hofstra University.

Sen. Ted Cruz (R-Texas) has campaigned in Manhattan, but not announced any events on Long Island.

Trump was in Wisconsin Saturday, and his campaign did not return requests for comment.

Steve Carl, owner of Carlyle on the Green in Farmingdale, said Saturday he was coordinating the event at Grumman Studios with Trump’s campaign.

Carl, a former Trump business partner, said the sound stage complex has ample space for the planned event. He said further information, including ticket availability, should be released Monday.

“It’s great for Donald to come back to New York and make an appearance,” Carl said. “It’s important the potential president knows Long Island exists.”
