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.

Republican Jewish Coalition CEO Matt Brooks began his remarks by asking the crowd to cheer in support of Israel.

"If someone tried that at the Democrat convention, they would be booed off the stage, but here at the Republican convention, we proudly and loudly stand with Israel," he said, to applause.

Brooks said the election is a "critical moment" for the American Jewish community and Israel, and said the Jewish community is ready to elect the Trump-Vance ticket.

"This is our chance to continue the incredible pro-Israel legacy of the most pro-Israel president in history," Brooks said.

During his remarks, Brooks displayed a red, Trump-branded yarmulke.

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.

Tennessee Gov. Bill Lee, the president of the National Governors Association, touched on Republican talking points -- from inflation to the border to parental rights -- while speaking on behalf of Republican governors.

"In the storm stirred by Washington, Republican governors across this country have stood as anchors of courage, their states as harbors of hope and their people as models of freedom," he said. "Governors can only do so much. We need strong leadership in the White House. We know what that looks like. We had it before, we need it again."

He said Republican governors are "joining together, unifying in support for Donald Trump for president."
