Secret Service Director Mark Sullivan announced his retirement Friday after a nearly-three decade career and seven years as head of the agency responsible for protecting the president, vice president and visiting foreign dignitaries.
The announcement comes nearly a year after a prostitution scandal during President Obama's trip to Colombia in April.
Secret Service spokesman Edwin Donovan confirmed the retirement, which becomes effective Feb. 23.
Sullivan was elevated to director of the agency and its 3,200 agents in 2006 after serving as deputy director and earlier as assistant director for all agency protective operations.
During Sullivan's tenure, he oversaw security for 23 national special events, including the last two presidential inaugurations. President Obama's first inauguration in 2009, which drew 1.8 million people to the capital, was largest gathering in Washington, D.C., history.
Sullivan's term also marked by scandal when a mix of Secret Service agents and military personnel were implicated for their involvement in procuring prostitutes in Cartagena, Colombia, last April in advance of President Obama's trip there.
A native of Arlington, Massachusetts, Sullivan began his Secret Service career as a special agent assigned to the Detroit field office in 1983, after having served for three years as a special agent in the Department of Housing and Urban Development's Office of Inspector General.
In 1991, Sullivan received his first assignment to the Presidential Protective Division, where he served for four years.
