Gov. Terry McAuliffe (D) is calling a special session of the General Assembly on August 17, 2015, to comply with a court order requiring legislators to redraw the state’s congressional map.

Last month, the 4th U.S. Circuit Court of Appeals ruled 2-1 for a second time Virginia must redraw the state’s congressional map by September 1, 2015. The court found the current map draws too many black residents into the 3rd Congressional District, which dilutes voting strength in other districts.

Republican leaders have asked the court to extend the deadline to November 16, 2015, in order to allow time for an appeal to the U.S. Supreme Court.
