Rep. Darrell Issa, California Republican and chairman of the House Oversight and Government Reform Committee, discusses a plan July 24, 2013, on Capitol Hill to move mail to cluster box and curbside delivery in a move to cut costs at the cash-strapped Postal Service by up to $4.5 billion a year. With the Postal Service facing billions of dollars in annual losses, the tradition of mail delivery to the door could be virtually phased out by 2022 under a proposal in Congress.
