Sarah Palin headlined four 'Liberty at the Ballot Box' bus tours, to raise money for candidates and the Tea Party Express. One of the tours visited 30 towns and covered 3,000 miles. Following the formation of the Tea Party Caucus, Michele Bachmann raised $10 million for a political action committee, MichelePAC, and sent funds to the campaigns of Sharron Angle, Christine O'Donnell, Rand Paul, and Marco Rubio. In September 2010, the Tea Party Patriots announced it had received a $1,000,000 USD donation from an anonymous donor.
Influence of Koch Industries
In an August 30, 2010, article in The New Yorker, Jane Mayer said that the billionaire brothers David H. Koch and Charles G. Koch and Koch Industries are providing financial and organizational support to the Tea Party movement through Americans for Prosperity, which David founded. The AFP's 'Hot Air Tour' was organized to fight against taxes on carbon use and the activation of a cap and trade program. Former U.K. ambassador Sir Christopher Meyer wrote in the Daily Mail that the Tea Party movement is a mix of 'grassroots populism, professional conservative politics, and big money', the last supplied in part by the Kochs. Mayer says that the Koch brothers' political involvement with the Tea Party has been so secretive that she labels it covert.
