Hunter Biden appeared in federal court in Los Angeles, California, on Thursday. The former lawyer, lobbyist and businessman was indicted in December. He is accused in nine counts, among other things, of evading federal taxes over several years. If convicted, Biden faces – at least theoretically – a long prison sentence. The allegations are at the heart of impeachment proceedings against the president sought by the opposition party. But they have so far not been able to present any evidence of wrongdoing on the part of Joe Biden.
