Barron Trump joins sister Tiffany and other Trump family members in nominating Donald for president...but one of his siblings is left off the list

Barron Trump is joining his siblings in nominating their father for president this summer but one famous family member has been left off the Florida delegate list.

Ivanka Trump, a Florida resident, is not one of the 125 delegates the state is sending to the Republican National Convention to formally nominate Donald Trump as the GOP presidential nominee.

The former first daughter has stepped away from politics and it's unclear if she'll even attend the event, which takes place in Milwaukee from Monday, July 15 to Thursday, July 18. 

However, Don Jr. and his fiancee Kimberly Guilfoyle, Eric Trump, Tiffany Trump and her husband Michael Boulos are all delegates at large along with younger brother.

Barron Trump was rarely seen during the Trump White House years, mainly at the request of his mother Melania who is known to be protective of her son

Lara Trump - Eric's wife - is vice chair of the Republican National Committee and will be at the convention in her official capacity. 

The Republican Party of Florida on Wednesday night picked Barron to join his older siblings for the event.

The only requirement to be a delegate is to live and vote in the state. Barron, who turned 18 in March, will be eligible to cast his first votes in the August primary and in the November election. 

But his first vote will be at the convention when he casts a vote for his father to be the party's nominee. 

Barron graduates from Oxbridge Academy in suburban West Palm Beach next week. That day - May 17th - will be a busy one for Donald Trump.

He's also scheduled to be the keynote speaker at Minnesota's Lincoln Reagan dinner. 

Barron's graduation ceremony is in the morning so it's feasible Trump could attend both events.  

During Trump's White House years Barron was rarely seen, mainly at the request of his mother Melania who is known to be protective of her son.

He was at his father's 2016 presidential announcement and attended the Republican National Conventions in both 2016 and 2020.  

But sources told DailyMail.com that the 6ft 7in teen, who has never uttered a word in public, is a steadfast supporter of the Trump 2024 campaign behind the scenes.

Delegates from a state typically sit on the convention floor together during the roll call of the states, where they vote for the party's nominee for president.

Eric Trump will serve as the Florida delegation chair, which means he will formally place his father's name in for the nomination for the state.

'We have a great delegation of grassroots leaders, elected officials and even Trump family members,' Florida GOP chairman Evan Power said. 'Florida is continuing to have a great convention team, but more importantly we are preparing to win Florida and win it big.'

In Trump's last two White House campaigns, Don Jr., Eric and Ivanka were heavily involved - speaking at their father's rallies and campaigning for him. Tiffany joined her siblings in the 2020 campaign but Barron stayed out of sight.

He was only 10 when his father became president. 

Ivanka, who served as a senior adviser to her father in his White House, made it clear she was out of politics when Donald Trump announced he was running for president again.

'I love my father very much,' she said at the time. 'This time around, I am choosing to prioritize my young children and the private life we are creating as a family. I do not plan to be involved in politics.' 

Barron, who turned 18 last month, returned to the spotlight with Donald Trump's hush-money trial when the former president argued he should be allowed a break from trial to attend Barron Trump's May 17 high school graduation. 

Judge Juan Merchan agreed to allow the break in the trial.

It's unclear what Barron's plans are after high school. He's lived in Florida since his father left the White House. 

Donald Trump won Florida twice - in the 2016 and 2020 elections. But Republicans in the state were in a tough spot in the 2020 GOP contest because Gov. Ron DeSantis was making a bid.

Ultimately DeSantis dropped out and endorsed Trump.

Now the slate of delegates to the Republican convention is filled with Trump loyalists: former state Attorney General Pam Bondi, longtime Trump adviser Sergio Gor, top Trump donors and loyalists who endorsed Trump over DeSantis.
