U.S. Secret Service Director Mark Sullivan, who is head of the agency that protects the president and other officials, will retire this month, a Secret Service spokesman said on Friday.
Sullivan, who was in charge of the agency when it was embroiled in a scandal involving prostitutes in Colombia last year, will step down on Feb. 22 after almost three decades with the service, spokesman Brian Leary said.
"The director is retiring," Leary said. "He's got almost 30 years of service so he's retiring. He's the third longest serving director."
Sullivan joined the Secret Service as a special agent with the Detroit office in 1983 and rose to become director of the agency in 2006.
Last year he went before Congress and apologized for the misconduct of employees who brought prostitutes back to their hotel rooms ahead of a visit by President Barack Obama to the Colombian resort of Cartagena.
It was the biggest scandal to hit the agency and set off several official investigations.
