A whistleblower report has raised concerns about the US Postal Service's efforts to develop a new system for verifying mail-in ballots. The report, disclosed by a Democratic senator, alleges that some procedures planned by the USPS have been kept hidden from the public. These procedures are part of initiatives driven by President Donald Trump.

Some officials within the agency have expressed concerns about the system, describing the process as problematic. The report suggests that the planned procedures could make the already complex and risky system more vulnerable.

Further details about the whistleblower report and the USPS's plans are available from the source, including concerns about the potential impact on the voting process.
