Trump angry he may miss son Barron's graduation, campaign events. Then announces NC rally.

Donald Trump fumed Monday that he may not be able to go to his son Barron's high school graduation ceremony due to the trial in New York, or campaign events or a key judicial proceeding for that matter.

But just hours later, the presumptive Republican presidential nominee's campaign announced he would hold a rally in Wilmington, N.C., this coming Saturday, April 20.

Nonetheless, Trump flared his anger at the Manhattan court case in remarks after Monday's proceedings concluded. Earlier in the day, the presiding judge, Juan Merchan, ruled that Trump will not be excused to attend arguments at the U.S. Supreme Court, and did not decide on his son's graduation ceremony next month.

"That I can't go to my son's graduation or that I can't go to the United States Supreme Court. That I'm not in Georgia, or Florida, or North Carolina campaigning like I should be," Trump said as he departed the Manhattan courtroom where jury selection began on Monday. "It's perfect for the radical left Democrats. It's exactly what they want."

The mention of the high court is a reference to next week's scheduled oral arguments on his claim that as president he enjoyed complete immunity from legal liability for any actions. It is an argument legal scholars have widely disparaged as unconstitutional.

The case filed against Trump in New York stems from what prosecutors say was a business fraud scheme to cover up an alleged hush money payment to a porn star in the weeks before the 2016 presidential election. Trump argues it is politically-manipulated to damage his 2024 White House campaign.

According to the timeline provided by the actress, Stormy Daniels, the alleged affair would have taken place when Barron was an infant.

Which son was Trump referring to?

Barron Trump is the youngest of Trump five children and his only child with Melania Trump. He celebrated his 18th birthday on Wednesday, March 20.

Trump has four other adult children: Donald Trump Jr., 46, Ivanka, 42, and Eric, 40, all with his first wife, Ivana, who passed away in July 2022. Trump also shares another adult daughter, Tiffany, 30, with his second wife, Marla Maples.

Barron Trump scheduled to graduate next month

In August of 2021, Barron enrolled at Oxbridge Academy, a fairly new school (founded in 2011) located off Military Trail just west of West Palm Beach, about eight miles from Mar-a-Lago. He is expected to graduate this May.

The Oxbridge Academy website lists graduation day as May 17, but does not specify a time. The former president owns a refurbished Boeing 757 in which he has flown across the country for rallies and presidential primary events this year.
