WaPo:

The federal government should start vetting companies that sell election systems as seriously as it does defense contractors and energy firms, a top election security group argues in a proposal out this morning.

Under the proposal from New York University’s Brennan Center for Justice, government auditors would verify election companies and their suppliers are following a raft of cybersecurity best practices. They would also have to run background checks to ensure employees aren’t likely to sabotage machines to help Russia or other U.S. adversaries.

The suggestion comes as Congress continues to fight over whether to tighten election security as candidates ramp up for the 2020 election. Senate Republicans, especially, have stalled further security measures, even as observers warn that the next election is ripe for hacking by foreign adversaries such as Russia, which interfered in the 2016 contest.
