The U.S. Supreme Court has agreed to delve once again into the controversial issue of limits on money in politics.

This time, it's the limits placed by federal law on how much an individual can contribute to candidates and political organizations.

The court today agreed to take up a challenge brought by an Alabama man who claims it's unconstitutional to prevent him from giving more than $46,200 to candidates and $70,800 to PACs and political committees. He does not challenge the limit on contributions to an individual candidate, but he does claim it's unconstitutional to prevent him from contributing to as many candidates as he wishes.

The Republican National Committee joins him in the challenge.
