Washington: The chairman of the Senate committee with jurisdiction over homeland security says he`s scheduled a hearing for May 23 to review the Secret Service investigation of the Colombia prostitution scandal.
Senator Joe Lieberman tells CNN`s "State of the Union" that he believes the agency has done a thorough job in investigating the incident. But the Connecticut independent also wants to know whether there were warning signs about agents` behaviour.
He also wants to hear what steps are being taken to ensure something similar doesn`t happen again.
Lieberman says the Secret Service director, Mark Sullivan, will be called to the hearing by the Senate Homeland Security and Governmental Affairs Committee.
