About 20 supporters of the post office rallied in downtown Columbia Thursday. Gathering outside Senator Claire McCaskill's office, supporters held banners and flyers opposing Senate bill 1789, which would cut funding to the U.S. Postal Service. They say a cut from 6 days to 5 days in service will slow down many deliveries. Eale Breedlove, a 30 year veteran of the postal service, says it could also put many veterans out of a job.
