In a viral video posted by attorney Will Chamberlain, which gained over 700,000 views in less than two hours, poll watcher Gary Feldman can be seen attempting to enter a polling station, only to be turned away by workers who claim his certificate 'isn't valid for this location.'

"Call the police!" says one poll worker, adding. "If you legal, call the cops."

"I have a city-wide watcher's certificate," said Feldman, to which another poll worker replied "That's not for this location."

Poll watchers are allowed to challenge the identity or residency status of a voter in the event they suspect fraud, along with inspecting voting machines and making sure poll workers aren't influencing the vote in any way.

The incident happened days after Pennsylvania Attorney General Josh Shapiro, a Democrat, tweeted: "If all the votes are added up in PA, Trump is going to lose."
