WASHINGTON (CNN) -- President Bush on Friday approved a Defense Department request to employ up to 50,000 U.S. reservists in military efforts expected to follow terror attacks on the United States, a White House official tells CNN.
Earlier, officials at the Pentagon said the Defense Department intended to seek authority to call up the reservists for "homeland defense."
The number would be drawn from all branches of the Reserve and National Guard armed forces, with the initial callup involving pilots and support for "strike-alert" operations.
Officials at the Pentagon also told CNN the callup would reinforce warplane patrols of American skies to defend military bases and any other possible targets against attack.
