WASHINGTON -- One of the staunchest Republicans in Congress, House Oversight Committee Chairman Darrell Issa (R-Calif.), attended a Capitol Hill memorial on Monday for progressive activist Aaron Swartz, praising the fallen Internet icon's political courage and saying he has common ground with much of Swartz's legacy."He and I probably would have found ourselves at odds with lots of decisions, but never with the question of whether information was in fact a human right," Issa said at the memorial.Swartz, who was one of the earliest minds behind Reddit, took his own life in January after fighting federal hacking charges for two years.
