CNN:

The US’s largest election equipment manufacturer has begun quietly lobbying Congress to force all voting equipment to create a paper trail, a sharp departure after years of selling paperless digital machines that can’t be fully audited. The change of stance comes amid concerns over the security of elections following Russia’s interference effort in the 2016 presidential election.
“There’s a big recognition today that auditing is important, and to do a proper audit you need a piece of paper,” Kathy Rogers, Election Systems & Software senior vice president of government relations, told CNN.
“I’ll tell you it’s a decision that came at a cost. We’ve lost a few sales because of it. But we think it’s the right thing to do,” Rogers said….

But critics say Election Systems & Software’s open pivot to paper is simply marketing, after the company saw that paperless machines were on the way out.
“After years of selling voting equipment that it knew was insecure, and fighting tooth and nail against real election security, ES&S is finally admitting that paper ballots are the most secure system currently available,” Sen. Ron Wyden, whose PAVE Act is one of the strictest security bills introduced in the Senate, told CNN in a statement.
“If it is serious about this change of heart, ES&S would tell its friends in Georgia and Speaker McConnell to stop standing in the way of the PAVE Act’s common-sense requirements to protect American democracy,” the Oregon Democrat said.
