You may be thinking of former Congressman Joe Scarborough, who had an intern who was found dead in his Pensacola, FL office.
Also, several congressmen were rumored to have frequented Condit's apartment for "parties". When law enforcement swept the apartment, they found multiple DNAs all over the place. This has all disappeared under various rugs now, but could probably be resurrected by simple investigation.
How did Scarborough's intern die? Homicide?
