Marshall Cohen for CNN:

Weeks before the 2022 midterms, a stranger showed up at the Denver headquarters of Dominion Voting Systems. He didn’t have an appointment, so the front desk asked him to leave. But staffers noticed him lingering outside, and one Dominion executive spotted a rifle case and scope in his vehicle.

A week later, the man returned, rambling about supposed problems with election security. He then said he had a pistol in his car. Alarmed, Dominion staff got the police involved and later obtained a restraining order.

The episode, described in court filings and by a senior Dominion official who spoke to CNN on the condition of anonymity, is part of the continued fallout from 2020 election lies. The impact has been acutely felt at Dominion, the voting technology company that became the poster child for baseless right-wing voter fraud claims in 2020.

The avalanche of disinformation forced voting companies and election officials to overhaul their approach for 2024, according to interviews with nearly a dozen people involved in running the election. They’ve ramped up investments in physical security, found new ways to combat false claims, and cracked down on employees’ political postings.
