A federal judge in Brooklyn became one of the first in the country on Monday to use a new federal law to order the immediate release of a man who served more than a decade in prison for his role in a drug trafficking conspiracy.

Senior U.S. District Judge Jack Weinstein wrote that Cheyenne Simons, the defendant, should be released immediately because of a new federal law that retroactively reduced the sentencing requirements for charges he had pleaded guilty to in 2008.
