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.
