8:00 p.m. - Signing off.

Saturday's rallies were the largest yet! News reports have put the number of Walker protesters at the Capitol today at 70-80,000 compared to 3-5,000 for Tea Party participants.

5:00 p.m. - TEA PARTY RALLY

Brendan Fischer reports on the Tea Party rally:

In what appears to be the largest day of protests yet, opponents of the budget repair bill filled the capitol square and paraded through packed streets while Walker supporters, Tea Party members, and conservative activists congregated in the state capitol's East spur. Approaching the spur at the height of the noon rally (organized by the Koch brothers' Americans for Prosperity), a deafening mix of competing chants ("Kill the bill!" "Pass the bill!" "Si se puede!" "What's disgusting? Union busting!") made it difficult to hear the speakers.

Madison, Wisconsin -- A new investigation by the Center for Media and Democracy documents the big money funneled by one of the richest men in America and one of the richest corporations in the world to put controversial Wisconsin Governor Scott Walker in office.

Tea Party groups are planning to attend a rally on Saturday, February 18 to show support for Scott Walker's effort to dismantle over fifty years of collective bargaining rights in his "budget repair bill." The rally is planned by the Koch brothers- funded Americans for Prosperity, the Sam Adams Alliance-funded American Majority, and several Wisconsin Tea Party groups.
