Trump, who campaigned for O’Connor's GOP opponent state Sen. Troy Balderson (R) ahead of the special election Tuesday night, declared victory after Balderson held onto a razor-thin lead in Ohio's longtime GOP-held 12th District.

“I don’t think he knows what he is talking about,” O’Connor said during an interview on CNN on Wednesday when asked what he thought of Trump's efforts to boost his opponent.

“You don’t walk our roads, you don’t have kids in our schools, you don’t deal with the public health crisis of addiction we have in our state every day,” he said.

O’Connor was trailing Balderson 49.3 percent to 50.2 percent with all precincts reporting on Wednesday morning, though the race remained too close to call, with thousands of provisional ballots still to be counted.

Regardless of the outcome, the close election has raised alarm bells for Republicans ahead of the November midterms, given that Trump won the Ohio district by 11 points in 2016.

O’Connor emphasized on CNN his independence from Washington, saying D.C. needs "new leadership."

“One thing I like to ask folks is what do they worry about, what keeps them up at night, and it’s rising health-care costs, it’s the thought of having their social security or Medicare cut,” O’Connor said.

He argued he could be an “independent voice” for his constituents on those key issues while arguing that Balderson would do “whatever Washington, D.C., tells him to do.”

O’Connor also took aim at establishment Democrats on Wednesday.

“We really need new leadership,” O’Connor said, explaining that the special election’s results show that “the same old politics aren’t working.”

“The desire to fight things out in the partisan nature instead of being pragmatic and finding solutions isn’t getting the job done for working families,” he said.
