House Democrats have warned of a nefarious plot by Postmaster General Louis DeJoy to slow mail service ahead of the Nov. 3 presidential election so many mail-in ballots don’t get counted. House Oversight Committee Chairwoman Carolyn Maloney and colleagues will have the chance to grill DeJoy in a hearing on Sept. 18.

The five-week time lag reflects a gap between what House Democrats say are efforts to thwart illegal and unconstitutional actions by President Trump and their actual schedule for doing so.
