D.C. blogger Mike Stark is circulating a video where he accuses House Minority Leader John Boehner of sleeping with a lobbyist—whom he names. Armed with a flipcam, Stark filmed his ambush at today's Pledge to America press conference.

Meet Lisbeth Lyons. She's the VP of Government Affairs for the Printing Industries of America. (Stark called them the "American Printers Association.") Mike Stark says "several sources" tell him she's having an affair with Boehner, but presents no further evidence or context.

Stark also has a recording of himself calling Lyons, who at first asks which publication he works for. (Answer: "Stark Reports, Huffington Post, Daily Kos.") She responds, "No comment." [Daily Kos, Stark Reports]
