Montana Shrugged, a tea party group, filed suit Thursday in U.S. District Court in Billings, naming as defendants the state political practices commissioner and Attorney General Steve Bullock.  The lawsuit, filed with the help of the James Madison Center for Free Speech in Terre Haute, Ind., says Montana laws requiring financial reporting by political committees and corporations are unconstitutionally vague.

Montana Attorney General Bullock stated the lawsuit is part of a nationwide plot to torpedo state laws that require public reporting on who funds political campaigns.  The lawsuit specifically challenges Montana’s restrictions on corporate contributions after a Montana court ruling last month overturned a law barring corporate independent expenditures and upheld the state’s restrictions on corporate contributions to political candidates.
