A lawmaker, a candidate and two donors have teamed up with the Institute for Justice to challenge a quirk in Minnesota's campaign finance law that limits individual donations to candidates.

According to the two-decade-old law, Minnesota candidates can only receive 20 percent of their money from high dollar donors, lobbyists, PACs or political funds. Once they reach that maximum, the amount they can receive from any individual drops and they are cut off from accepting lobbyist, PAC and political fund money.

The federal suit below says that the law is an unconstitutional limit on free speech.
