WASHINGTON (AP) - President Bush signed a bill approved by Congress on Friday to keep the government operating while lawmakers struggle through their year-end spending work.

The bill - the third this fall - will keep federal agencies open through Nov. 21. By that time, congressional leaders hope all 13 annual spending bills will be finished and Congress can adjourn for the year.

The Senate approved the latest temporary bill by voice vote Friday and shipped it to the White House. The House had passed the legislation on Wednesday by 418-5.

The government's new budget year began on Oct. 1. So far, Congress has completed only four of the 13 annual bills.
