Question: The 9/12 Tea Party was a political rally sparked after a 2009 call from which reporter?

Related documents: [0]  [DOC] The movement began following Barack Obama's first presidential inauguration (in January 2009) when his administration announced plans to give financial aid to bankrupt homeowners. A major force behind it was Americans for Prosperity (AFP), a conservative political advocacy group founded by businessmen and political activist David H. Koch. It is unclear exactly how much money is donated to AFP by David and his brother Charles Koch. Following a February 19, 2009 call by CNBC reporter Rick Santelli on the floor of the Chicago Mercantile Exchange for a "tea party," over fifty conservative activists agreed by conference call to coalesce against Obama's agenda and scheduled series of protests, including the 2009 Taxpayer March on Washington. Supporters of the movement subsequently have had a major impact on the internal politics of the Republican Party. Although the Tea Party is not a party in the classic sense of the word, some research suggests that members of the Tea Party Caucus vote like a significantly farther right third party in Congress.
