NEW YORK, NY November 20, 2008 —Since the 9/11 attacks the NYPD and federal law enforcement have made progress collaborating on counter-terrorism efforts. But with the changing of the guard in Washington, old tensions between police Commissioner Ray Kelly and homeland security officials are are re-emerging. WNYC's Bob Hennelly reports.

REPORTER: Kelly and Attorney General Robert Mukasey are at odds over how best to handle NYPD terror suspects who've popped up on the city's radar.

Law enforcement sources say Kelly believes the Justice Department has prevented the NYPD from submitting warrant applications to the Foreign Intelligence Surveillance Court in Washington. The court deals with the most sensitive national security issues and its proceedings are secret.

The Department of Justice did not return calls for comment, but the agency and the Bush administration in the past have been reprimanded in the Federal courts for over-reaching in counter-terrorism cases. For WNYC I'm Bob Hennelly.
