A year later, he was reassigned to the position of Deputy Assistant Director, Office of Human Resources and Training. In 2006, Sullivan was appointed by George W.

On February 1, 2013, Sullivan announced he was retiring after 30 years with the agency to be effective February 23.^[2]

After his retirement, Sullivan partnered with Noah Kroloff, Dennis Burke, David Aguilar, John Kaites and Jerry Reinsdorf to found Global Security and Innovative Strategies.^[3]

In April 2012, a scandal involving the President's security detail received international press attention. The scandal involved 11 agents and more military personnel from all four branches who allegedly engaged prostitutes while assigned to protect President Barack Obama at the 6th Summit of the Americas in Cartagena, Colombia. As of April 24, nine employees had resigned or retired.^[4][5]

Starting June 30, 2011, agents on the Presidential Protection Detail were ordered to leave their posts and conduct surveillance on a neighbor of Lisa Chopey, Sullivan's assistant, in an operation named "Moonlighting". This continued for at least several days and according to some accounts, months. The neighbors eventually moved away, they said partly because of the intimidation.^[6]
