"
"Warren and Klobuchar co-signed letters sent to investors of the three major voting systems used in the U.S. last December, including a Dominion investor. A letter sent to the managing directors of the private equity firm Staple Street Capital Group, LLC, which was also signed by Oregon Senator Ron Wyden and Representative Mark Pocan of Wisconsin, requested information on what the nature of the firm's financial relationship with Dominion was.

The letter drew attention to a handful of incidents during the 2018 midterm elections in which voters reported that the machines they used switched their votes, raising concerns about the machines' security and the importance of updating voting machine technology whenever possible."
