RNC 2024 Day 2: Trump feted by former rivals Haley, DeSantis in show of GOP unity

West Virginia Gov. Jim Justice took the stage with his dog, Babydog, who trotted out and took a cushioned seat to the governor's right.

Justice, who's running as a Republican for the Senate seat that Democrat Joe Manchin will vacate, said, "We'd become totally unhinged if Donald Trump is not elected."

"He genuinely cares. He cares about all of us," he said of Trump. "He loves this nation beyond good sense."

Justice also said Donald Trump Jr. is a "treasured friend" and that Eric Trump once replaced his tire.

He also said Babydog has predicted that Republicans will win back the White House and Senate and keep control of the House.

Trump is again expected to make an appearance at the RNC arena tonight, sources with knowledge of his schedule told ABC News.

Reince Priebus, the former RNC chair and Trump's chief of staff, took the stage, welcoming the crowd to Wisconsin.

He stressed Trump's accomplishments, stating: "While president, he decided to drill, baby, drill. He shut down the border, he confronted China head-on, made Europe pitch in on NATO, lowered taxes, put conservatives on the Supreme Court and he defeated ISIS."

Priebus, who also chaired the Wisconsin GOP, stressed how important the state is for Trump's victory.

"Let's stand united as Republicans. Let's stand united as Americans. Let's make America one again," he said.

Hayden Padgett, chairman of the Young Republicans, praised Trump and his 39-year-old running mate, Sen. J.D. Vance, as a strong ticket for young people. Under Trump's first term, Padgett said, a bright future was promised.

"That future is diminishing as quickly as Biden's cognitive ability," he claimed, adding that young Americans are crippled under rising costs of education, groceries and housing.

"Our founders did not promise us happiness but the right to pursue it. And the Biden-Harris administration took that all away from us," he said.
