The FBI and other law enforcement officers fanned out across the region on Friday, executing a number of search warrants involving a local union boss and a Philadelphia city councilman. Agents were searching the home of Johnny "Doc" Dougherty, a bar called Doc's Union Pub, the headquarters of the International Brotherhood of Electrical Workers Local 98 and Councilman Bobby Henon's offices. Just recently, Action News has learned Local 98 dropped upward of $80,000 on lavish parties and events for honchos and lobbyists at the Democratic National Convention.
