Joe Biden on Wednesday flatly refused to answer a question about whether he should have stopped his son Hunter from doing business in Ukraine in a field in which he had zero experience.

“My son’s comments speak for themselves,” he said during a press briefing a day after he defended him during Tuesday’s Democratic presidential debate.

Asked Tuesday about President Trump’s allegation that Hunter Biden was guilty of corruption for taking a seat on the board of directors of Burisma Holdings that paid him up to $50,000 a month even though he had no experience in the energy field or doing business in Ukraine, the former veep bristled.

“Look, my son’s statement speaks for itself. I did my job. I never discussed a single thing with my son about anything having do with Ukraine,” he said during the debate in Ohio.

Hunter Biden has said he “did nothing wrong at all,” while admitting he likely wouldn’t have gotten the lucrative gig if he weren’t the vice president’s son.

“I don’t know. I don’t know. Probably not, in retrospect,” he told ABC News in a weekend interview that aired Tuesday. “But that’s — you know — I don’t think that there’s a lot of things that would have happened in my life if my last name wasn’t Biden.

“Because my dad was vice president of the United States. There’s literally nothing, as a young man or as a full-grown adult that — my father in some way hasn’t had influence over. It does not serve either one of us,” he continued.

Hunter Biden’s lawyer, George Mesires, said Hunter would not serve on the boards of foreign-owned companies if his father wins the 2020 presidential election.

The president and his lawyer, Rudy Giuliani, have charged that Joe Biden threatened to withhold US aid to Ukraine if the country didn’t fire a prosecutor who had once investigated Burisma.

Meanwhile, a July 25 Trump call to Ukrainian President Volodymyr Zelensky, in which he asked him to open probes into the Bidens and supposed 2016 election meddling by Ukraine, has sparked an impeachment inquiry by House Democrats.
