US Navy expelled Vice-President Biden’s son after positive cocaine test

US Vice-President Joe Biden's son was discharged from the US Navy after testing positive for cocaine, an official said.

Hunter Biden, 44, had been a reserve officer since 2012 but failed the drug test last year, said the official familiar with the case.

In a statement, the vice-president's younger son acknowledged his discharge and expressed regret.

"It was the honour 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 in the statement.

"I respect the navy's decision. With the love and support of my family, I'm moving forward."

There was no public response from the vice-president's office.
