WASHINGTON (AP) — Hunter Biden, the youngest son of Vice President Joe Biden, has been expelled from the military after testing positive for cocaine, two people familiar with the matter say.

The Navy said that Biden, a former lobbyist who works at a private equity firm, was discharged in February — barely a year after he was selected for the part-time position as a public affairs officer in the Navy Reserve. Citing privacy laws, the Navy did not give a reason for the discharge, which was not disclosed until it emerged in the media on Thursday.
