Court records show that the leader of a Southern California labor union arrested while protesting an immigration raid will have his felony obstruction charge reduced to a misdemeanor. An acting U.S. Attorney wrote in a court filing Friday that David Huerta had been charged with obstruction, resistance or opposition to a federal officer, which is a class A felony. However, prosecutors filed a proposed order Saturday seeking dismissal without prejudice of the original felony charge of conspiracy to impede an officer. Huerta’s union represents hundreds of thousands of janitors, security officers and other workers across California. His attorneys say Huerta is being singled out for “being a life-long workers’ advocate."
