The Supreme Court appeared sharply divided on the question of whether there's any limit on what the courts can impose on partisan redistricting, also known as gerrymandering, with Justice Brett Kavanaugh, the newest member of the court, appearing at least somewhat conflicted.

A Spanish court says assailants who broke into North Korea's Embassy in Madrid last month later fled to the U.S.

According to new documents unsealed on Tuesday, the perpetrators of the attack included a U.S. citizen and another resident. The leader of the plot fled via Lisbon to Newark, N.J., and offered stolen material to the FBI in New York.

The first of more than 1,600 lawsuits pending against Purdue Pharma, the maker of the opioid OxyContin, has been settled.

The drugmaker has agreed to pay $270 million to fund addiction research and treatment in Oklahoma and pay legal fees.

Bump stocks — the gun add-ons that can dramatically increase their rate of fire — are now officially illegal in the U.S., after a Trump administration ban took effect Tuesday. Anyone selling or owning bump stocks could face up to 10 years in federal prison and a fine of $250,000 for each violation.

Chief Justice John Roberts declined to hear an appeal from gun makers on the new ban Tuesday, allowing it to remain in place. A separate appeal that seeks a stay on enforcing the ban is before Justice Sonia Sotomayor.
