It's one thing to suspect it and quite another to have it confirmed. Mother Jones reports that outgoing Daily Caller Executive Editor David Martosko had quite the career impersonating liberals in order to infiltrate and disrupt their organizations while he worked for PR hack RIck Berman.
Before Daily Caller Editor in Chief Tucker Carlson hired him in 2011—a controversial choice given Martosko's previous arrests and lack of experience in journalism—Martosko spent a decade working for Richard Berman, a longtime PR operative behind a number of industry-backed campaigns. At Berman and Company, Martosko served as the director of research for the Center for Consumer Freedom, a Berman-run nonprofit that opposes new laws on food and beverages. CCF, which is funded by the food and beverage industry, runs Humane Watch, a website that posts derogatory information about the Humane Society of the United States. Martosko was the site's "founding editor." CCF also operates Activist Cash, a website that compiles biographical information on groups and individuals that engage in "anti-consumer activism."
In the 2011 deposition, Martosko acknowledged he used a Facebook account under the name of "Gregory Davis" (later changed to "Preston Davis") to obtain information about animal rights activists. (You can read the full deposition here.) Read the rest...
Martosko didn't stop there. He went on to intentionally disrupt the organizations he was spying on.
