WASHINGTON-The Supreme Court for a second time blocked Missouri from using a congressional map in the November midterm elections that the state GOP redrew to benefit Republicans.

The court issued a brief order Thursday to end a dispute that Justice Brett Kavanaugh had already tried to settle earlier this week. No justices recorded any dissent, and the order came less than an hour after Missouri Republicans submitted a legal brief seeking to use their preferred map.

That unusually rapid timing suggested the justices were eager to send a message about the last-ditch bid by Republicans to circumvent a prior ruling from the state's highest court, which deemed the pro-GOP map invalid.

Missouri's legislature voted to redraw its congressional districts last year amid a mid-decade redistricting push across the country as Republicans and Democrats battled for control of the House of Representatives. The new map would have given GOP candidates an advantage in seven of the state's eight House districts.

Last week, the Missouri Supreme Court said the redrawn districts can't be used unless voters approve them in a ballot referendum. On Tuesday, Kavanaugh rejected an emergency appeal from Missouri Republicans and declined to disturb the state court's ruling. Kavanaugh, who fields emergency requests from Missouri and surrounding states, didn't refer the matter to the full court-a sign that he didn't believe it raised a serious legal issue.

But minutes after being notified of Kavanaugh's action, a federal judge in a different case nevertheless restored the Republican-favored districts, setting off a lightning-quick flurry of new proceedings that rushed back up to the Supreme Court.

The legal fight has created last-minute electoral chaos, with candidates and voters unsure of who would be on the ballot in which districts. The now-invalidated map was used in the state's primary, and officials now face a scramble in finalizing congressional contests for Election Day.
