The younger Biden told ABC News that he "served honorably" on the board and did nothing unethical; however, he said he may have made a "mistake" by giving "a hook to some very unethical people to act in illegal ways to try to do some harm to my father."
"Did I do anything improper? No, not in any way. Not in any way whatsoever," he told the news outlet.
He added that he regrets "not taking into account that there would be a Rudy Giuliani and a president of the United States that would be listening to this ... ridiculous conspiracy idea."
Hunter Biden also told ABC News that he "didn't have any discussions" with his father about the board after the younger Biden became involved with it. But he did call his dad after the transcript was released, he said.
After the elder Biden asked how Hunter's daughter was doing, they briefly shared their reactions, Hunter Biden said.
"And then discussion was literally, like, 'Oh my gosh,'" the younger Biden said. "But other than that, really, I want to make it clear, it's not like anybody has to have any discussion beyond that."
