COLORADO SPRINGS, COLO. -- As hundreds of residents rushed to file their taxes last-minute Tuesday, dozens rallied in Colorado Springs in protest of where taxpayer dollars go.

On Tax Day, several postal workers and activists rallied outside City Hall to spread the word that the U.S. Postal Service does not receive tax dollars.

"We're trying to alert the public that no tax funds go to the postal service," Kathy Corcoran, a letter carrier, said. "It is all rate payer money that funds the postal service, and we want to keep the postal service strong and vibrant."

Protesters were also armed with a unified message that the proposed post office closures will cut thousands of jobs across the country, including hundreds in Colorado Springs.

"There's 350 jobs at stake, and we need to be out here to support these folks and try to retain these jobs in Colorado Springs," city councilman Tim Leigh said.

Representatives from the offices of Sen. Michael Bennett, Mayor Steve Bach and the American Postal Workers Union were on hand for the rally. Others from bipartisan organizations, such as the NAACP, also came to show their support, and many signed petitions in the fight to stop the closure of many post office locations.

"We're concerned about our customers," Corcoran said. "We're concerned about the delay in mail their going to receive."

Just like a chant heard during Tuesday's rally, Corcoran believes if Congress broke it, Congress can fix it.

"If Congress would just relieve us of the $5 billion prefunding of our health benefit plan, that no other company has to do," she said, "we'd be in good shape."
