Cocaine user booted from Navy

From CNN.com

A U.S. Navy reserve officer was kicked out of the Navy after he tested positive for cocaine. Big deal, eh?

As it turns out, it is a big deal.

The guy is Vice-President Joe Biden's son. He was just commissioned as an Ensign in the Navy last year. But get this. He is 44 years old!

When do most people go into the Navy? Wouldn't after college be the usual step? Why was Hunter Biden commissioned as an Ensign in May 2013?

What do you suppose the whole story is about his connection with the Navy?
