The Supreme Court has denied Remington Arms Co.'s bid to block a lawsuit filed by families who lost loved ones in the Sandy Hook school massacre. The families say Remington should be held liable, as the maker of the AR-15-style rifle used in the 2012 killings.

The court opted not to hear the gunmaker's appeal, in a decision announced Tuesday morning. The justices did not include any comment about the case as they turned it away.

Remington had appealed to the highest federal court after the Connecticut Supreme Court allowed the Sandy Hook lawsuit to proceed in March.

Former President Jimmy Carter is to undergo surgery in Atlanta on Tuesday morning to relieve pressure on his brain that was caused by bleeding from two recent falls, the Carter Center says.

Carter, 95, was admitted to Emory University Hospital on Monday evening for the procedure. He was accompanied by his wife, Rosalynn.
