Unfounded rumors are swirling — some of them promoted by President Trump — as ballot counting enters its third day.

The claims have drawn responses from elections officials trying to quell misconceptions and conspiracy theories.

False: Using a Sharpie will invalidate your ballot. This one was circulating in both Arizona and Pennsylvania, prompting officials to clarify that ballots filled out with a Sharpie or other marker will indeed be counted. If the machine cannot read a ballot because ink has bled through from the other side, it will be handed off to a human reader, they said.

Some conspiracy theorists said that poll workers in Arizona’s Maricopa County were handing Sharpies to Trump voters in an attempt to invalidate their ballots. The county’s election officials said that fine-tip Sharpies were indeed being used at some polling places —  for all voters, not just apparent Trump supporters — because the ink dries fast and is less likely to smudge. The county had even specified in pre-election materials that Sharpies were fine to use.

Facebook said it has blocked the Sharpiegate hashtag on its platform and pointed to fact checks on the matter.

False: More people voted in Wisconsin than were registered. This rumor ran wild on social media, with people throwing around figures like “101% voter turnout” and “110,000 more ballots than voters.” PolitiFact and other fact-checking sources ruled it baseless, and added that Wisconsin allows same-day voter registration, so any comparison of previous voter numbers and ballots cast was likely to indicate a discrepancy.

False: Wisconsin “found” 100,000 votes for Biden at 4 a.m. Wednesday. “We are not ‘finding ballots.’ Ballots are being counted,” said Julietta Henry, Milwaukee County director of election. What some labeled a “ballot dump” was just a standard update of the count, which had gone on through the night, she said. The surge for Biden was largely the result of a batch of mail-in ballots from Milwaukee, a Democratic stronghold.

False: A Fox TV station in Detroit uncovered voter fraud, including thousands of dead people registered to vote. The screen image being circulated was from a 2019 report on an advocacy group’s complaint about inaccurate voter rolls. The group dropped its lawsuit after “remedial action” by Detroit elections officials.

False: A man in Virginia Beach was caught on video burning ballots marked for Trump. Eric Trump was among the social media users circulating this false claim. Elections officials in Virginia Beach, Va., investigated the video and found that it showed sample ballots, not real ballots. The officials’ statement included a freeze frame that showed the ballots lacked the barcode that is on the official ones. Facebook has flagged the video as misinformation.
