WASHINGTON (AP) _ The Supreme Court is signaling it probably will reject a Republican appeal over congressional districts in Virginia. The court’s liberal justices sounded skeptical Monday about a challenge brought by Republican members of Congress who want the Supreme Court to reinstate a districting map that had been tossed out by a lower court. The lower court said Virginia illegally packed black voters into one district to make adjacent districts safer for Republican incumbents. A 4-4 tie would uphold the lower court ruling.
