Jones was attacked by conservatives for statements he made against Republicans and for signing a petition in 2004 that questioned whether George W. Bush allowed 9-11 to occur to help start a war in the Middle East.
"I have been inundated with calls -- from across the political spectrum -- urging me to 'stay and fight.' But I came here to fight for others, not for myself.
