Citizens United wants to promote "Hillary: The Movie" without disclosing the names of donors, as required by the federal McCain-Feingold Act.

The group earlier asked a three-judge panel in Washington for a preliminary injunction that would have allowed it to ignore a prohibition against corporations and unions from paying for ads, including broadcast ads, that name a candidate before an election. The group had argued that the film didn't tell voters how they should vote, The Washington Post reported.

When the three-judge trial panel rejected the injunction request, the group appealed directly to the U.S. Supreme Court. The justices rejected the appeal, 07-953 Citizens United vs. FEC, saying it was "dismissed for want of jurisdiction." The court added that Justice Stephen Breyer would have affirmed the judgment of the three-judge panel.

Since the case hasn't gone to trial, Citizens United could appeal to the federal circuit court in Washington.

While the anti-Clinton movie is circulating on the Internet, the group is preparing a similarly critical movie on her Democratic presidential rival Sen. Barack Obama, D-Ill., Scotusblog.com reported.
