A super PAC supporting the comeback bid of former Nebraska Democratic Sen. Bob Kerrey debuted its first round of television ads on Friday.

The group's first spot takes aim at state Sen. Deb Fischer, Kerrey's Republican opponent, and her family's enrollment in a federal grazing program that has drawn scorn for subsidizing only a few Nebraska farmers.

The super PAC, End the Gridlock, has numerous connections to Kerrey. The group's treasurer, Michael Tucker, worked as Kerrey's spokesman when he headed the Democratic Senatorial Campaign Committee, and several key donors also have ties to the candidate.

Less than two weeks ago, Kerrey called on Fischer to agree to reject super PAC spending in the race, but Fischer declined.

Fischer's campaign lashed out at Kerrey for gaining super PAC support so soon after expressing frustration over the influence of the outside groups.
