The United States Postal Service is appealing to Congress for $89 billion in federal grants, warning that without assistance, the coronavirus pandemic will leave the agency insolvent by September. The appeal came after the Trump administration successfully blocked a $13 billion direct grant to the Postal Service in the $2.2 trillion coronavirus relief bill, instead offering the agency a $10 billion loan. Postmaster General Megan Brennan says that’s not enough to prevent disruption of regular mail delivery by the fall. The looming crisis comes as many states are looking to expand voting by mail ahead of the November election. In a tweet, Vermont Senator Bernie Sanders urged Congress to act to save the USPS.
