Wilbur Mills. Never mind.
More to the topic would be Wayne Hays.
On the Democrat side, there is a straight line from the Clintons back to the earliest modern DC sex scandal. In 1974, the powerful Chairman of the House Ways and Means Committee Wilbur Mills (D-AR) was caught with stripper Fanne Foxe (the "Tidal Basin Bombshell) when he was pulled over at 2:00am for a DUI. Mills represented Little Rock for 38 years. When Mills resigned, Clinton buddy Jim Guy Tucker (then Arkansas Attorney General) succeeded Mills in Congress, and Clinton took Tucker's seat as Attorney General. Clinton eventually became Governor, and when he became President Tucker left Congress and became Governor after Clinton.Of course, this is all ancient history for most people today, but it shows how Arkansas is Democrat Ground Zero for all sorts of scandals. Wilbur Mills is Patient Zero. Two years later, Wayne Hays (D-OH) became infected when he was caught paying his "secretary" Elizabeth Ray ("I can't type, I can't file, I can't even answer the phone.") for two years to be his mistress.
