ST. LOUIS, MO – September 5, 2026 (STL.News) Federal scrutiny of the U.S. Postal Service in the St. Louis region intensified Friday as congressional oversight officials toured a major St. Louis mail processing facility with Postmaster General David Steiner following years of complaints involving delayed mail, missing packages, medications, checks and election-related mail.
U.S. Rep. Ann Wagner, R-Mo., said House Oversight officials came to St. Louis on Friday, Sept. 4, after she formally requested a congressional investigation earlier this year. House Oversight Subcommittee on Government Operations Chairman Pete Sessions toured the St. Louis Processing Center with Steiner as part of the congressional review.
The visit represents one of the most significant steps yet in a prolonged effort by Missouri lawmakers to determine why postal service across the St. Louis metropolitan area has experienced persistent problems despite previous audits, recommendations and promises of corrective action.
“Our St. Louis community deserves on-time mail delivery from the United States Postal Service,” Wagner said following Friday’s visit, adding that residents have reported problems receiving paychecks, medications and ballots.
Wagner said the visit was an important step but would not end congressional scrutiny of USPS operations in the region.
Postal problems have persisted for years
The current congressional investigation did not begin with a single complaint or isolated delivery failure.
USPS Office of Inspector General audits have documented significant operational problems at St. Louis-area postal facilities.
In 2025, the inspector general conducted a congressionally requested review of the St. Louis Processing and Distribution Center, the Network Distribution Center, and seven delivery units serving communities throughout the metropolitan area.
Those delivery units included facilities serving Ballwin, O’Fallon, St. Charles, Clayton, Creve Coeur and several St. Louis neighborhoods.
The inspector general identified deficiencies in five of six areas examined. Problems included delayed mail, clearance times, late or canceled outbound transportation, scan compliance, and security issues involving registered mail.
One finding was particularly significant.
According to the USPS inspector general’s fall 2025 report to Congress, auditors found approximately 2.6 million delayed pieces of mail at the St. Louis Processing and Distribution Center. The inspector general described it as the largest amount of delayed mail discovered since its field operations review program began in 2022.
The audit of the St. Louis Processing and Distribution Center resulted in recommendations addressing staffing, management accountability, processing operations, maintenance, transportation and the reporting of delayed mail.
Among other actions, the inspector general recommended that USPS develop a plan to hire and retain enough employees, hold managers and supervisors accountable for enforcing workplace rules, improve preventive maintenance, and ensure delayed mail is accurately reported each day.
The problems were not entirely new.
A separate 2022 inspector general review of St. Louis-area operations also identified deficiencies affecting mail delivery, customer service and postal property conditions. That review found problems involving delayed mail, package scanning, truck-arrival scanning and transportation.
The repeated findings have increased congressional concerns that the St. Louis area’s postal difficulties are systemic rather than temporary.
Wagner pushes Congress for greater USPS accountability
Wagner’s office says she has pursued the St. Louis postal issue since at least February 2024 through congressional letters, meetings with USPS officials and requests for inspector general reviews.
In March 2026, Wagner formally asked the House Oversight Committee to investigate USPS implementation of previous inspector general recommendations, management accountability, the agency’s responsiveness to Congress and its preparations for handling election mail.
The pressure has also produced bipartisan legislation.
Rep. Wesley Bell, D-Mo., and Wagner introduced the St. Louis Postal Accountability and Reform Act, known as the STL Up To PAR Act, on April 30.
The legislation would require USPS to submit a report to Congress detailing mail and package delivery performance throughout the St. Louis region.
Under the proposal, USPS would be expected to report performance compared with national averages, workforce vacancy and turnover rates, progress implementing inspector general recommendations and management systems intended to prevent similar failures from recurring.
Bell said constituents have described waiting weeks for prescription medications, benefit checks and utility notices.
“The mail delays in the St. Louis region have gone on for far too long,” Bell said when the legislation was announced.
The measure demonstrates the bipartisan nature of the St. Louis postal controversy.
Bell introduced H.R. 8599 with Wagner and Reps. Emanuel Cleaver of Missouri, Mike Bost of Illinois, and Nikki Budzinski of Illinois. It was referred to the House Committee on Oversight and Government Reform.
Dumped mail leads to additional investigation
Congressional concerns escalated further after a large amount of undelivered mail was discovered in a vacant lot in north St. Louis on April 29.
Local reporting documented hundreds of envelopes in a pile near Maffitt and North Taylor avenues, including mail addressed to residents throughout St. Louis and Ferguson. Some of the mail reportedly carried postmarks dating back to January.
USPS said at the time that it was investigating how the mail ended up there and intended to attempt delivery.
The incident subsequently became part of a separate congressional investigation led by U.S. Sen. Josh Hawley, R-Mo.
Hawley announced June 30 that his office was investigating what he described as systematic USPS service failures in Missouri, as well as possible criminal activity involving abandoned mail and executive bonuses within the Postal Service.
During a Senate hearing, Hawley showed Steiner a photograph of dumped mail discovered in north St. Louis. According to Hawley’s office, Steiner testified that it was the first time he had heard about the incident.
Hawley subsequently demanded USPS documents and communications related to service failures and executive compensation.
That Senate investigation is separate from the House Oversight effort that brought Sessions and Steiner to St. Louis Friday.
Mail theft and check-washing allegations add concerns
Another issue involving the St. Louis postal system has attracted federal attention.
In May, Wagner requested an FBI investigation after the Madison County Sheriff’s Office in Illinois raised allegations involving mail theft and check washing connected to USPS processing operations in the St. Louis region.
According to Wagner’s office, local investigators reported difficulties obtaining cooperation and information from USPS personnel while investigating the alleged crimes.
Wagner asked federal authorities to investigate the allegations.
Her office said Friday that the FBI subsequently informed her that its St. Louis Field Office assigned a special agent to support and oversee a USPS Office of Inspector General investigation.
The allegations remain under investigation, and allegations of criminal conduct should not be interpreted as findings of wrongdoing against any individual USPS employee or official.
Election mail has also drawn congressional attention
Problems involving election mail have made the St. Louis postal controversy particularly sensitive.
Wagner’s office said postal problems affected Franklin County’s April 2025 municipal election, when 350 absentee ballots arrived too late to be counted. Some reportedly were not delivered until months after the election.
Concerns about election mail had already prompted Wagner and other Missouri lawmakers to request an audit of eastern Missouri postal operations in September 2024.
That request asked USPS officials to examine the Hazelwood sorting operation and explain reported failures involving election mail.
With federal elections approaching in November 2026, USPS’s ability to reliably process election-related mail is likely to remain a major focus of congressional oversight.
What happens next for St. Louis mail service?
Friday’s tour does not by itself resolve the St. Louis region’s postal problems.
Instead, it puts senior USPS leadership and congressional investigators directly inside the facility at the center of many of the concerns.
The key question now is whether operational changes implemented after the inspector general audits have produced measurable improvements.
Congressional investigators could seek additional documents, testimony, performance data, or explanations from USPS management as the House Oversight review continues.
Lawmakers are also seeking more transparency through the STL Up To PAR Act, which would create a formal reporting requirement for St. Louis-area postal performance if enacted.
Meanwhile, Hawley’s Senate investigation continues to focus on service failures, abandoned mail, possible criminal activity, and USPS executive compensation.
Together, the inquiries create an unusually high level of federal scrutiny of postal operations in the St. Louis metropolitan area.
For residents, however, the ultimate measure of success will be considerably simpler: whether letters, bills, checks, prescriptions, packages and ballots arrive when they are supposed to.
Wagner said Friday that congressional attention will continue beyond the facility visit.
The St. Louis postal system has now been examined by the USPS inspector general, challenged by members of both political parties, and investigated in both chambers of Congress.
What comes next will depend on whether USPS can demonstrate that the problems documented by federal auditors have been corrected—and whether St. Louis-area customers begin seeing those improvements in their mailboxes.
