From 1882 to 1968 "...nearly 200 anti-lynching bills were introduced in Congress, and three passed the House. Seven presidents between 1890 and 1952 petitioned Congress to pass a federal law." None was approved by the Senate because of the powerful opposition of the Southern Democratic voting bloc. In June 2005, through passing a bipartisan resolution sponsored by senators Mary Landrieu of Louisiana and George Allen of Virginia, the US Senate officially apologized for not having passed an anti-lynching law "when it was most needed."
