Andrew Breitbart Dead at 43

Andrew Breitbart, publisher, commentator, and new-media advocate who helped build the Drudge Report and the Huffington Post in addition to his own aggregation sites, has died. His site BigGovernment.com reported that Breitbart passed away from natural causes in Los Angeles early Thursday morning. The self-described “Reagan conservative” was born and raised in Los Angeles before going on to earn his bachelor’s degree at Tulane University. “I’m committed to the destruction of the old media guard,” Breitbart said in a 2010 interview. “And it’s a very good business model.” Few details are known about his death, though the L.A. coroner's office tells ABC News that is happened shortly after midnight.
