Day three of the Republican National Convention centered around vice presidential candidate JD Vance as he introduced himself to Republicans as Trump's running mate.

The day was held under the theme of "Make America Strong Once Again."

Former President Donald Trump made an appearance at the convention hall to watch his running mate make his national debut. Other notable speakers included Trump's son and granddaughter and several Gold Star families who expressed their support for the former president.

Despite calls for unity, several speakers spent time bashing President Joe Biden, Vice President Kamala Harris and the Democrats on several issues including immigration, crime and Israel.

East Palestine mayor praises Trump's support after toxic train derailment

East Palestine, Ohio, Mayor Trent Conaway took the stage, praising the first responders who rushed to help after a freight train carrying hazardous materials derailed last year.

He criticized the federal response, claiming the Biden administration "talked and talked, but they delivered little help."

Conaway went after Biden for not visiting the town in the immediate aftermath and praised Trump for coming to the town less than three weeks after the incident.

"I know a thing or two about train wrecks now and let me tell you, that is what the Biden administration has been," he said.

In an exclusive interview with ABC News anchor David Muir in February 2023, Biden said he "made it clear" to officials on the ground that "anything they need, we'll make it available to them."

The comments came after East Palestine's mayor called it a "slap in the face" that Biden traveled to Ukraine while his town felt forgotten in the weeks after the crisis. Biden went to East Palestine a year later.

He defended his orders that the Texas National Guard install razor wire across parts of the Texas border and his policy of bussing migrants out of Texas and north. (A narrowly divided Supreme Court in January sided with the Biden administration in a tense, ongoing dispute over the Texas-Mexico border and razor wire fencing installed by the state that had prohibited federal border agents from performing their duties.)

"The president's most sacred duty is to secure our country," Abbott said. "Joe Biden deserted his duty," the governor argued.

"It is time to restore order at the border, to rid our streets of crime and chaos; it is time to secure our nation by returning Donald Trump as president of the United States of America," he said.
