Hunter used the government for 411 trips while Joe was VP.
Per the Wall Street Journal
“Mr. Biden, 44 years old, decided to pursue military service relatively late, beginning the direct-commission process to become a public-affairs officer in the Navy Reserve in 2012. Because of his age—43 when he was to be commissioned—he needed a waiver to join the Navy. He received a second Navy waiver because of a drug-related incident when he was a young man, according to people familiar with the matter. Military officials say such drug waivers aren’t uncommon.
Mr. Biden was commissioned as an ensign on May 7, 2013, and assigned to Navy Public Affairs Support Element East in Norfolk, Va., a reserve unit, according to the Navy. In June 2013, after reporting to his unit in Norfolk, he was given a drug test, which turned up positive for cocaine, according to people familiar with the situation. Mr. Biden was discharged in February, the Navy said.”
Dime to a dollar, some of Hunter’s corruption was during this period.
