Washington Post:

A Nov. 9 article incorrectly described Supreme Court nominee Samuel A. Alito Jr.’s opposition to a federal firearms law banning the possession and sale of machine guns. The U.S. Court of Appeals judge’s 1996 dissent said Congress had no power to pass the law in question under the Constitution’s commerce clause, saying there was no evidence that the mere possession of a machine gun affected interstate commerce. Alito did not say that such laws would be unconstitutional under all circumstances.
