Secret Service Director Mark Sullivan, who served under two presidents, steps down on Friday after a long reign at the head of the agency.
Sullivan, who had been director since 2006, had a successful run as director, but his tenure was not without heartburn.
He had to deal with the couple who crashed a White house party in 2009, and last year, his agents were involved in a sex scandal involving prostitutes in Colombia.
He was an agent for 30 years.
