Attorney James Bopp, who's a key architect of the legal battle that's led to a flood of outside spending in elections, has registered a new independent expenditure only committee with the Federal Election Commission called the Republican Super PAC Inc.

The filing, which is signed by Bopp and lists him as treasurer, was dated May 11, 2011. 

Bopp represented and then worked as a legal adviser to Citizens United, the political committee that was the plaintiff in the 2010 Supreme Court case that found that corporations could spend unlimited money on independent expenditures to influence elections. He was removed as lead counsel from the case in January 2009 in favor of less ideological counsel, according to the New York Times. 

In the 2010 election, the Citizens United decision and the related Speech Now vs. FEC case led to a flood of spending by outside groups–some $454 million. More than $126 million of that total came from committees that did not disclose donors.
