Postmaster General Louis DeJoy has agreed to testify before Congress next week amid the uproar over changes at the U.S. Postal Service that Democrats say are designed to interfere with the November election by making it harder to vote by mail. Louis DeJoy is a major Trump donor. House Democrats are planning to return to Capitol Hill on Saturday to vote on legislation blocking the recent changes. Over a dozen states are now expected to sue the Trump administration, and California Congressmember Ted Lieu is calling on the FBI to launch an investigation.
