An Ohio sheriff ordered residents to keep a list of homes where campaign signs supporting Democratic presidential candidate Kamala Harris and her running mate Tim Walz were displayed, amid unrest on social media.

Bruce D. Zuchowski, the Republican sheriff of Portage County, posted the comments on his personal and professional Facebook pages on Friday, warning that undocumented immigrants would arrive if Harris were elected over his party’s nominee, Donald Trump.

“When people ask me… What’s going to happen if the Flip-Flopping, Laughing Hyena wins??” Zuchowski wrote, referring to Harris. “I say… Write down all the addresses of the people who had her signs in their yards!”

Zuchowski called immigrants “illegal human ‘locusts’” and added: “We already have the addresses of their new families … who supported their arrival!”

In the same post, Zuchowski included screenshots of several Fox News stories claiming the Biden administration’s immigration policies were fueling a “crime wave” and “destroying small towns.”

At least two commenters said they would collect the addresses of neighbors who openly supported the Democratic nomination, the Portager, a local newspaper for the area, reported.

Zuchowski has since restricted the ability to comment on the post. He did not respond to the Guardian’s request for comment.

Fox News’ coverage included photos of Aurora, Colorado, and Springfield, Ohio, two small towns that made national headlines after Trump and his running mate, J.D. Vance, spread false claims about immigrants in those cities.

Zuchowski’s comments drew widespread criticism, including from fellow Republicans.

Portage County Commissioner Tony Badalamenti publicly condemned the post and resigned from the county’s Republican central committee in a video he posted to Facebook, Portager reported.

“This is not the leadership I want to be part of,” Badalamenti said.

Referring to Zuchowski’s actions, Badalamenti added: “It scares people. It’s called bullying, from the highest law enforcement in Portage County, the sheriff’s office.”

Others condemned Zuchowski’s comments as a form of voter intimidation, especially given the sheriff’s high position in law enforcement.

The American Civil Liberties Union of Ohio said it had received several complaints from Portage County voters about Zuchowski’s post, Ohio’s WOSU Public Media reported.

“This past weekend, we’ve had people contact us and say they feel intimidated and they’re considering changing their behavior. I don’t want to say they should change their behavior, but maybe they shouldn’t put signs in their yards,” Collin Marozzi, deputy policy director for the ACLU of Ohio, told WOSU.

Zuchowski is running for re-election on Nov. 5, the same day as the presidential election. His Democratic challenger, Jon Barber, said Zuchowski’s comments could undermine trust between the public and law enforcement.

“People here shouldn’t have to be afraid that if they call the police — ‘Are they going to look at my voting record? Are they going to look at whether I have a sign that says I support someone they don’t like or a position they don’t like? And then they’re going to drive away instead of helping me,'” Barber told WOSU.
