WASHINGTON - The Senate has approved a commemorative postal stamp, the revenue from which will help families of rescue workers who died during the terror attacks Sept. 11.

Sen. Hillary Rodham Clinton, a New York Democrat who helped win Senate approval for the stamp late Wednesday in an amendment to a spending bill, said last week that it would be a tribute to "acts of bravery and sacrifice."

A companion measure was introduced in the House, which could take action today.

The 45-cent stamp will depict rescue workers digging through the rubble of the World Trade Center, said Jordan Goldes, a spokesman for Rep. Gary L. Ackerman, a New York Democrat. Eleven cents of each stamp's cost would go to a relief fund created by the Federal Emergency Management Agency for the families of rescue workers.
