Sen. Russ Feingold (D-Wis.) appears to have a love interest.
The lawmaker, who is single, was spotted strolling hand in hand around Capitol Hill with a mystery woman on Tuesday night.
His companion was a trim, short-haired blonde who looked to be in her early 40s.
Feingold had changed out of his formal suit into a bluish polo shirt and khaki pants. The woman was wearing jeans and a blue T-shirt.
Feingold’s office declined to comment.
