Secret Service director retiring, agency says

(CNN) - U.S. Secret Service Director Mark Sullivan will step down this month, concluding a long career that was clouded last year by a scandal at the agency involving agents and prostitutes ahead of a presidential summit in Colombia.

Spokesman Brian Leary said on Friday that Sullivan would retire on February 22 after leading the agency that protects presidents and fights financial crime since 2006. He's been an agent for 30 years.
