The conservative activist responsible for producing an undercover video showing a National Public Radio senior executive slamming the Tea Party as "racist" and "scary" is speaking out about why he went after the organization. And late Tuesday, NPR announced it has placed the executive, Senior Vice President for Fundraising Ron Schiller, on administrative leave. Filmmaker James O'Keefe said the idea for the sting stemmed from an incident in October when NPR fired analyst Juan Williams after he said he got scared when people wore Muslim garb on airplanes.
