During the Ohio recount in 2004, Catherine Buchanan says she was told Diebold reprogrammed voting machines while present at her local Board of Elections. "They told us that Diebolt [sic] was coming to reprogram the computer, which doesn't make any sense. I mean, if you're going to calibrate a machine, you calibrate it before you're going to do testing to make sure it's going to be okay," Buchanan asserts.

ES&S

Tom Eschenberger, vice president of ES&S, was fingered by charges of bribery and kickbacks.
