CLEVELAND (CBSNewYork/AP) — Donald Trump is officially the Republican presidential nominee.

Trump secured the delegates for the nomination during the traditional roll-call of states Tuesday night at the Republican National Convention in Cleveland.

The New York delegation put Trump over the top. Trump’s son Donald Jr. cast the final votes his father needed to become the Republican presidential nominee.

The younger Trump was on the floor of the convention and told the excited activists in the auditorium that New York was casting 89 votes for Trump and six for Ohio Gov. John Kasich.

He then shouted out: “Congratulations, Dad, we love you.”

Also on the convention floor are some of Donald Trump’s other children, including Eric Trump and Ivanka Trump.

Delegates on the floor broke into cheers and waved signs as the song “New York, New York” played at the Quicken Loans Arena.

Donald Trump called it a “great honor.”

Despite the celebration, there is drama on the convention floor as Alaska is contesting the recording of the nomination vote.

But House Speaker Paul Ryan has declared that Alaska’s 28 votes are going to Trump — who already had more delegates than he needed to win.

The dispute appeared to be over Alaska state party rules that say a candidate loses his or her delegates if the candidate’s campaign is no longer active.

All of Trump’s challengers suspended their campaigns when it became clear the New Yorker would win the nomination.

Ryan said Trump received 1,725 delegates in the state-by-state roll call. Ryan says Texas Sen. Ted Cruz was the runner-up with 475 delegates. Ohio Gov. John Kasich came in third with 129 votes, followed by 113 for Florida Sen. Marco Rubio.

Fifth-place went to physician Ben Carson with seven delegates, followed by former Florida Gov. Jeb Bush with three delegates and Kentucky Sen. Rand Paul with two delegates.

Indiana Gov. Mike Pence has also been nominated as the Republican vice presidential candidate — and Trump’s running mate.

Speaking via satellite from Trump Tower, the new nominee said “we have to go all the way.”

“This is going to be a leadership, by the way, that’s going to put American people first,” Trump said.

He added that “it’s an honor” to run on a ticket with Pence and that he will make a great vice president.

The theme of the convention’s second day is “Make America Work Again,” with speeches focusing on jobs and the economy. Speakers include Ryan, New Jersey Gov. Chris Christie, and former Republican candidate Dr. Ben Carson.

CBS2’s Marcia Kramer reported Trump Jr., and daughter, Tiffany Trump, will take the stage to extol their dad in hopes to put to rest another campaign controversy.

It was revealed that parts of Melania Trump’s speech from Monday night may have been plagiarized from Michelle Obama’s 2008 speech at the Democratic National Convention.

Trump campaign chairman Paul Manafort denied the accusations of plagiarism.

“There are not that many similarities,” Manafort said. “It’s basically three places in the speech and it’s fragments of words.”

Hofstra University political expert Larry Levy called it a “distraction.”

“It’s another distraction away from what the Trump campaign is trying to do,” Levy said. “Once they figure out who wrote the speech, I guarantee you that Donald Trump will be saying, ‘You’re fired.'”

New Jersey Gov. Chris Christie is among those scheduled to take the stage.

In a change of plans, Hofstra University is now set to host the first debate. It was originally supposed to be held at Wright State University in Ohio, but that school had second thoughts because of security concerns.
