WASHINGTON (AP) - President Barack Obama's national intelligence director, Dennis Blair, says he is resigning after 16 months in the job.
In a message to his work force, Blair says his last day will be May 28.
Blair, a retired Navy admiral, is the third director of national intelligence, a position created in response public outrage over the failure to prevent the Sept. 11, 2001, terrorist attacks.
Blair's tenure was marked by intelligence failures and turf wars among the country's spy agencies.
