Democratic presidential candidate Joe Biden acknowledged it "may have looked bad" for his son to serve on the board of foreign companies, but the former vice president stood firm that his son did nothing wrong.

"What may have looked bad but wasn't anything wrong is totally different than whether a president has held up $400 million in aid for the Ukrainian military when Ukrainians are dying," Biden said during an interview with Telemundo released Thursday. "That is criminal."


Biden's son Hunter, who served on the board of a Ukrainian gas company in 2014, is tangled in a key element of Democrats' impeachment efforts against President Donald Trump, who pushed Ukrainian officials to investigate the Biden family.
