From AP News:

The U.S. intelligence community will now be able to store information about Americans with no ties to terrorism for up to five years under new Obama administration guidelines.

Until now, the National Counterterrorism Center had to immediately destroy information about Americans that was already stored in other government databases when there were no clear ties to terrorism.

Giving the NCTC expanded record-retention authority had been called for by members of Congress who said the intelligence community did not connect strands of intelligence held by multiple agencies leading up to the failed bombing attempt on a Detroit-bound airliner on Christmas 2009.
