The U.S. Secret Service has done little to fix database vulnerabilities that allowed agents to improperly access and leak personal information about House Oversight and Government Reform Chairman Jason Chaffetz, according to a follow-up report by the Homeland Security Office of Inspector General released Friday evening.

“Today’s report reveals unacceptable vulnerabilities in Secret Service’s systems,” Inspector General John Roth said in a statement. “While Secret Service initiated IT improvements late last year, until those changes are fully made and today’s recommendations implemented, the potential for another incident like that involving Chairman Chaffetz’ personal information remains.”
