In April of 2011 SF Chronicle staffer Carla Marinucci captured on videophone a group of protestors at an Obama event and posted it with her story.The next day Phil Bronstein, the Chronicle’s editor at large, exposed Marinucci was told by the White House that she would be barred from future Bay Area coverage of the president’s visits. The White House denied threatening the reporter which prompted this amazingly frank statement by Chronicle editor Ward Bushee.
