Thy name is Norm Coleman:

In a press conference this morning, Sen. Norm Coleman’s campaign said they are suing their opponent Al Franken for false attacks against him. They will submit the lawsuit to the Bureau of Administrative Hearings later today.

The campaign claims Franken violated the law in recent TV and radio ads by knowingly running false attacks against a political candidate running for office. The campaign says they will take appropriate civil and criminal sanctions against Franken.
