Joe Biden’s son was booted from the military after failing a drug test, it was revealed Thursday.

Hunter Biden, the youngest son of the vice president, was discharged from the Navy Reserve in February after he tested positive for cocaine, the Navy said.

Hunter, a former lobbyist who works at an investment firm, had been commissioned as an ensign in the Navy Reserve, The Wall Street Journal said.

The service did not give a reason earlier this year when it discharged the 44-year-old Biden barely a year after he was selected for the part-time position as a public affairs officer in the Navy Reserve.

He needed one waiver to join the Navy because of his age. He also received a second Navy waiver because of a drug-related incident when he was a young man, according to The Wall Street Journal.

The former ensign released a statement through his attorney Thursday, but did not address the drug use.

“It was the honor of my life to serve in the US Navy, and I deeply regret and am embarrassed that my actions led to my administrative discharge,” he said.

He added he respected the Navy’s decision and was moving forward with his family’s support.

Hunter’s brother, Delaware Attorney General Beau Biden, has spent time in the Delaware Army National Guard.

The vice president speaks highly of Beau’s stint in the military during campaign events.

But at an American Legion hall last year, Vice President Biden took time to crack a joke about his 40-something going off to join the military.

“We have a lot of bad judgment in my family,” the vice president said, according to The Wall Street Journal.

“My son, who is over 40, just joined the United States Navy. He’s about to be sworn in as an officer, Hunter Biden.”
