The son of U.S. Vice President Joe Biden has been discharged from the military, reportedly after testing positive for cocaine.
Media reports on Thursday quoted people familiar with the situation as saying Hunter Biden failed a drug test in June last year.
The Navy Reserve, where Biden was a public affairs officer, confirmed the discharge occurred in February, but did not give a reason.
In a statement, the 44-year-old Biden said he deeply regrets and is embarrassed at his actions, but said he respects the Navy's decision.
The vice president's office has not responded to the discharge, which was first reported Thursday by The Wall Street Journal.
Biden, a junior officer who carried the rank of ensign, is a former lobbyist who also works at a private equity company.
He is the younger brother of Beau Biden, who is the attorney general of Delaware.
