Officials in Maricopa County, Arizona, the nation’s fourth-largest county, said Tuesday they have been planning for years to secure polling locations and the tabulation center on Election Day.

The county, which has been at the center of election conspiracy theories and threats since 2020, will conduct one of the nation’s most intense security operations with mounted patrols and drones for surveillance and security cameras, according to the Maricopa County Sheriff Russ Skinner.

Skinner told reporters there haven’t been “a lot of threats” this year, but he expects to see more as Election Day approaches and in the days that follow.

“There is no place in politics or in this process where criminal activity is allowed and there is no tolerance that we as public safety accept any type of criminal act or any type problem that arises,” Skinner said. “We want this to be a safe and secure process.”

During the press conference, Maricopa County Supervisor Bill Gates said an individual with a hidden camera recently recorded a county training and posted videos and photos of election workers on social networks social.

“Election workers are banned, they should be,” Gates said. “They should not be threatened. Their names and images should not be published. And I am convinced that we are not going to see that from now on.”

Gates added that the county had received more than 1 million early ballots and said that for the first time since 2006 there would be a two-page ballot, meaning it will take longer than usual to fill out the ballots.

The county has increased the number of voting booths and staff to alleviate long lines at the polls.
