The National Security Agency is scaling back the way it spies on some communications over the Internet.
The NSA says it discovered what it called "lapses" in compliance with U.S. law.
They're called "about" communications: The NSA not only watches messages traveling to and from a foreign target, but those that mention one.
That can mean the NSA sometimes sweeps up data from Americans without a warrant. In the past, officials said the spy agency was still mindful of citizens' privacy.
