From Wikipedia:
Karl Denninger is the former CEO of MCSNet in Chicago, one of the area's first Internet providers.
He is most notably, however, a founding contributer to conservative blog market-ticker.org and is one of the early members of the Tea Party movement ("I cannot take credit for the idea floated on the forum, but I do like it.").[1]. Rick Santelli's CNBC mention of a tea party[citation needed] followed Mr. Denninger's Blog entry on January 20th.
On January 20, 2009 Denninger published an article regarding the suggestion to mail tea bags to the white house and to congress. The title of his post was "Tea Party February 1st?," and it was written in direct response to President Obama's inauguration occurring on the same day, even though he openly voted for Obama. The article took issue with the bailouts, the US national debt and "the fraud and abuse in our banking and financial system" which included the predatory lending practices currently at the center of the home mortgage foreclosure crisis.[2]
Karl Denninger, who helped form FedUpUSA in the wake of the March 2008 Federal Reserve bail out of Bear Sterns, has been a guest on MSNBC, Glenn Beck and CNBC Reports.[3][4] By February 1, the idea had spread among various conservative and libertarian-oriented blogs, forums, websites and through a viral email campaign.[5]
On Oct 20, 2010, he blogged that Republicans had hijacked the Tea Party movement, and perverted its original goals to the standard Republican concerns of "guns, gays and God."[6].
Denninger stated on RT that he supports the Occupy Wall Street movement.[7]
