False claims, retweeted by the president, about the Michigan vote tabulation exploited a counting error that’s been resolved.

While votes are still being counted in Michigan, President Trump retweeted a claim that an update in Michigan’s vote count yielded 138,339 votes for Joe Biden and 0 for Trump. The tweet that the president amplified — which was later deleted — included side-by-side screenshots from the Decision Desk election map that appeared to show an unusual jump. In reality, though, there was no conspiracy: A data glitch had momentarily caused the count to change.
