NEW YORK (AP) -- Civil libertarians in New York City have begun an appeal of a federal judge's decision that found the National Security Agency's collection of Americans' phone records is legal.
Lawyers for the American Civil Liberties Union filed the notice of appeal on Thursday in the 2nd U.S. Circuit Court of Appeals.
The judge's decision last week concluded the NSA program is a necessary extension of security measures taken after the Sept. 11, 2001, terrorist attacks.
An earlier ruling by another federal judge had granted a preliminary injunction against collecting the phone records of two people who had challenged the program.
Government lawyers haven't responded. A Department of Justice spokesman said last week he was pleased the court found the NSA's collection program to be lawful.
