Postmaster General Louis DeJoy will appear before the House Committee on Oversight and Reform on Wednesday for a hearing on the financial footing of the U.S Postal Service.

"The Postal Service's financial condition has been deteriorating over the past decade due to a number of factors, including a decline in first-class mail and the requirement to pre-fund retiree health benefits. The Postal Service needs legislative relief to meet its financial challenges," the committee said in a statement.

"The Committee will consider draft legislation that includes several provisions to relieve the financial burdens under which the Postal Service is currently operating and to enhance transparency regarding performance. The current draft includes provisions on Medicare integration, repealing a requirement for the Postal Service to pre-fund retiree health care, and service performance standards."

DeJoy is expected to face questions about the Postal Service's poor on-time delivery rates.

Several other figures -- including Tammy Whitcomb, the inspector general of the USPS, and Mark Dimondstein, the president of the American Postal Workers Union -- will also appear as witnesses before the committee.
