The United States Postal Service is not doing a very good job of delivering the mail, according to the results of an audit conducted by its Inspector General.
For the 12-month period ending February 28, 2017, mail processing facilities under-reported the amount of late-arriving mail by about 2 billion pieces.
Employees of the USPS are also accused of manipulating data and employee time sheets to make it look like more mail is being delivered than is actually the case, according to the audit.
The USPS has denied the charges.
A number of Senators have taken up the debate, expressing concern and requesting changes at the USPS.
Five of the eight processing and distribution centers did not accurately report the amount of delayed mail, according to the audit.
Delays in mail reporting cost the post office $85 million in lost revenue.
