Vice President Joe Biden's son Hunter Biden was discharged from the Navy Reserve in February after testing positive for cocaine, according to media reports. According to the Wall Street Journal, which broke the story Thursday, Hunter Biden had been commissioned as an ensign in the Navy Reserve in May 2013.

The position was part time and Biden, a lawyer by training, continued working as a managing partner in an investment firm.

In a statement to CNN, he said: “It was the honor of my life to serve in the U.S. Navy, and I deeply regret and am embarrassed that my actions led to my administrative discharge. I respect the Navy's decision. With the love and support of my family, I'm moving forward.”

ABC News reports that Biden, 44, had needed an age waiver to join the Reserve because of his age as well as a second waiver because of a drug-related incident he was involved with as a young man.

A person familiar with the case said that in respect of his dismissal, he “was treated no different than any other sailor.”

Hunter Biden is Joe Biden's second son, and is married with three children. The vice president's other son, Beau Biden, is the attorney general of Delaware and currently considered a front-runner in the 2016 race for governor of the Diamond State, according to MSNBC
