Washington (CNN) -- Two more Secret Service members have resigned over a Colombia prostitution scandal, the agency said Tuesday, while another member is being forced out and two more were cleared of serious misconduct. The latest resignations brought to nine the total number of members who have resigned or are being forced out because of the controversy, with three others cleared of the most serious allegations but still facing possible administrative discipline. A total of 24 people -- 12 Secret Service members and 12 U.S. military members -- were under investigation in the alleged prostitution scandal. Military officials are carrying out a separate investigation of their personnel.
