Rabbi David Nesenoff has given Accuracy in Media the most detailed account yet of how his encounter with veteran White House correspondent Helen Thomas caused him to reevaluate not only his view of the media, but of the White House and President Obama. Nesenoff is a self-described liberal Democrat who used to think Obama should be given a chance to change U.S. foreign policy for the better. Now he worries about the existence of the state of Israel.
