Activist groups rallied in White Plains Saturday as part of the nationwide Save the Post Office movement.

They called on Postmaster General Louis DeJoy to resign in the wake of mail slowdowns and on Congress to "protect and save the post office from Donald Trump."

Post office leadership is facing criticism for possible changes and cuts, which many say threatens the United State Postal Services' ability to handle a surge in mail-in ballots.

On Friday, DeJoy testified in front of the Senate, saying the Postal Service "is fully capable and committed to delivering the nation's election mail securely and on time." However, he did not promise to restore mailboxes or sorting machines that were already removed.

Activists say the demonstration will show Americans coming together to stand up for a postal system that connects them and that they can rely on.

Congressional candidate Mondaire Jones recently joined with a group of politicians to sue President Donald Trump over the recent changes and now says it's all hands on deck.

In a rare Saturday vote, the House approved legislation that would reverse recent changes in U.S. Postal Service operations and send $25 billion to shore up the agency ahead of the November election.
