David Brock, MM's founder, was quoted Saturday by Politico promising that his organization is mounting "guerrila warfare and sabotage" against Fox News, which he said "is not a news organization. It is the de facto leader of the GOP, and it is long past time that it is treated as such by the media, elected officials and the public.”

To that end, Brock told Politico that MM will “focus on [News Corp. CEO Rupert] Murdoch and trying to disrupt his commercial interests ..." Murdoch is the founder of Fox News and a media titan with newspaper, broadcast, Internet and other media countries around the world.

There is nothing in the Politico article to suggest that Brock, who was paid just under $300,000 in 2009, according to the group's most recently available tax return, plans to ask the IRS to change his organization's tax status as a 501(C)(3) tax-exempt educational foundation.

Being a C3 puts MM in the non-profit, non-commercial sector, and it also bars the organzation from participating in partisan political activity. This new, more aggressive stance, however, appears to run directly counter to the government's requirements for maintaining a C3 tax status.
