Blogger Michael Petrelis learned that NPR news staffers Corey Flintoff and Michelle Trudeau donated to the campaigns of John Kerry and Howard Dean, violating NPR’s ethics codes. In a response to Petrelis, NPR Ombudsman Jeffrey Dvorkin addressed the issue in his latest online column, and the Chicago Reader takes it up as well. Meanwhile, NPR reporter Eric Weiner writes in the Christian Science Monitor that Palestinians should practice nonviolence. Other NPR reporters have previously sounded off on current events, raising questions about proper ethical conduct.
