Facing public backlash, Postmaster General Louis DeJoy has told a Senate panel that it’s his “sacred duty” to ensure election mail delivery.

But he told senators on Friday that he has no plans to restore curbside mail collection boxes or high-speed sorting machines that have been removed.

He said they're not needed.

The committee is digging into service changes he made ahead of the November election, just as millions of Americans are expected to vote by mail.

Democrats warn DeJoy’s cost-cutting initiatives are causing an upheaval that threatens voting.

President Trump raised the stakes by saying he wants to block funds to make it harder for the Postal Service to operate.

Republican Sen. Ron Johnson, the chairman of the Senate Homeland Security committee, is expected to dismiss the “false political narrative” that DeJoy is trying to “sabotage” the election, according to prepared remarks.

Democratic Sen. Jacky Rosen from Nevada pressed DeJoy for transparency on the changes he's making at USPS. (read comments below)
