WASHINGTON, Oct. 15 (UPI) -- Advocacy groups are preparing for Saturday's "No Kings" rallies throughout the United States to call for government accountability and public vigilance under the current administration.

Republican leaders, though, are characterizing the planned mass protests as unpatriotic and disruptive, despite organizers' emphasis on peaceful protest. Talking points have advised them to call it the "Hate America Rally."

In the days leading up to the nationwide protest, organizers from groups like the American Civil Liberties Union, Public Citizen and the Federal Workers Union Network say they've been finalizing logistics and outreach for what is expected to be one of the largest single-day demonstrations in U.S. history.

Katherine Garcia, the press officer at Public Citizen, said the week leading up to the No Kings demonstration has been extremely busy, as Public Citizen is one of No Kings partners.

"We're extremely proud of all of the work that all of the organizers have put into motion to make this day possible," Garcia said. "No Kings will be a peaceful protest, so one of our top priorities is making sure that organizers on the ground are fully prepped to tackle any issues -- even any glimpses of violence from outsiders.
