In West Virginia:

A canvass is underway today to make sure all votes are correctly tabulated. During that process, officials discovered at least two USB flash drives that contained the ballots for multiple precincts, but were never plugged into a computer for counting. https://t.co/Kma1rG1TtB

KANAWHA COUNTY, w.va. (WSAZ) — UPDATE 11/13/18 @ 10:53 a.m.
Officials are no longer calling the hundreds of ballots that fell through the cracks in Kanawha County a machine error, but a human error.

More than 1,700 votes in Kanawha went uncounted on Election Day, leading to questions in some tight races. The affected precincts were in the Elkview, Clendenin, and Pinch areas as well as Kanawha City.

Originally, the clerk’s office said it was due to machine error — an error they discovered when the machines and hand-written number of voters did not match up.

A canvass is underway Tuesday. Officials are sorting through paperwork and making sure all votes are correctly tabulated.

During that process, officials discovered at least two USB flash drives that contained the ballots for multiple precincts, but were never plugged into a computer for tabulation. That would have been a duty at the clerk’s office.

Officials chose random precincts to canvass. There could be more, but they started with Holz Elementary, Piedmont Elementary, Rock Lake Presbyterian Church, Point Harmony Elementary, Sissonville’s Loftis Fire Station, and Shoals Elementary.
