The White House threatened [on April 28] to exclude The San Francisco Chronicle from pooled coverage of its events in the Bay Area after the paper posted a video of a protest at a San Francisco fundraiser for President Obama last week, Chronicle Editor Ward Bushee said. White House guidelines governing press coverage of such events are too restrictive, Bushee said, and the newspaper was within its rights to film the protest and post the video. Chronicle senior political reporter Carla Marinucci was invited by the White House to cover the Obama fundraiser on April 21. About 200 donors paying $5,000 to $38,500 each attended the event at the St. Regis Hotel in the city, a day after Obama visited Facebook headquarters in Silicon Valley touting the proliferation of new media" breaking the confines of traditional journalism. At the St. Regis event, a group of protesters who paid collectively $76,000 to attend the fundraiser interrupted Obama with a song complaining about the administration's treatment of Pfc. Bradley Manning, the soldier who allegedly leaked U.S. classified documents to the WikiLeaks website.
