WASHINGTON (AP) — A U.S. official says the head of the top counterterrorism agency is resigning after nearly five years at his post, now that one of the nation's major counterterror goals has been met with the killing of Osama bin Laden last month.

Michael Leiter presided over a reorganization of how counterterrorism information is shared, after the 2009 attempted bombing of a Detroit-bound airliner was blamed on a failure to share intelligence among government agencies.

The official says with bin Laden dead, Leiter wants to leave on a high note. There's no word yet on a replacement for Leiter at the National Counterterrorism Center. The official spoke on condition of anonymity because the White House has not announced the resignation.
