SAN FRANCISCO, Oct. 15 (UPI) -- A California non-profit is urging sponsors to pull their ads from Fox News Channel, because of "a would-be assassin inspired by" Fox personality Glenn Beck. The Tides Foundation, which says it promotes human rights, justice, and a healthy, sustainable environment, has come in for frequent criticism on Beck's show. A suspect in a July 28 shootout with police, Byron Williams, told police in an affidavit he had intended to go to the Tides Foundation's office in San Francisco and kill founder and Chief Executive Officer Drummond Pike.
