Oct 13 (Reuters) - Inside the El Paso County clerk's office in Colorado, where officials had gathered in July to recount votes in a Republican nominating contest for this year's midterms, dozens of angry election watchers pounded on the windows, at times yelling at workers and recording them with cell phones.Protesters had mobilized outside the clerk's office, holding signs with the signature "Stop the Steal" slogan of former President Donald Trump and demanding the county get rid of its voting machines.During early voting in Arizona's Pima County, an election observer was told to put away binoculars; another was caught looking at private voter data, and another was asked to stop making comments about “fraudulent elections,” according to a September report by the county recorder's office reviewed by Reuters.Pima county recorder Gabriella Cazares-Kelly said her election staff received multiple complaints from voters that individuals were shouting at them from outside the 75-foot circumference around polling stations, where interaction with voters is banned.During the call, which Reuters attended, participants compared notes on how to observe the testing of voting machines and when a hand count of votes can be requested, and discussed the legality of taking photographs in polling locations."
