CHICAGO (WLS) -- Starting Monday, you can help fulfill the Christmas wishes of local children in need.
The U.S. Postal Service is kicking off its annual "Operation Santa" program. Just stop by the main post office downtown, 433 W Harrison St., and pick up a letter to Santa Claus written by a child.
