The billboards are all in swing or Republican-leaning districts. The targets: GOP Reps. Andy Barr (Ky.), Dan Benishek (Mich.), Steve Daines (Mont.), Rodney Davis (Ill.), Jeff Denham (Calif.), Tom Latham (Iowa), Steve Southerland (Fla.), Jackie Walorski (Ind.), Dan Webster (Fla.) and Bill Young (Fla.).
The National Republican Congressional Committee fired back.
