MADISON, Wis. -- A Wisconsin group protesting a landmark U.S. Supreme Court campaign finance ruling will stop using the name "Citizens United" in a petition protesting the decision after being asked by that group not to.

Instead, the Wisconsin Democracy Campaign will call its petition "United Citizens Against Citizens United."

The group announced the change on Thursday, just four days after receiving a letter from a Citizens United attorney asking that the name on the petition and Facebook page be changed.

Democracy Campaign officials said in a blog post that it doesn't believe there is a legitimate trademark infringement case against using the name, but it decided to change it to remove any questions about whether the two groups are related.
