A roundup of some of the most popular but completely untrue stories and visuals of the week:

ClaimThe election database in Maricopa County in Arizona has been deleted, seals were improperly broken on boxes that hold the votes and ballots are missing.

The factsAn unprecedented, partisan audit of the 2020 election in Arizona's largest county is being used to spread false information about the vote.Though a partial hand recount and two extra audits found no issues in the election that gave Biden a margin of victory of less than 10,500 votes in the battleground state, Republicans in the Arizona state Senate used their subpoena power to take possession of all 2.1 million county ballots, the machines that counted them and hard drives full of data, and hired a Florida-based cybersecurity firm to comb through it.The firm, Cyber Ninjas, is run by a supporter of former President Donald Trump who has promoted election conspiracy theories. On May 12, Senate President Karen Fann sent a letter to the chairman of the Republican-controlled Maricopa County Board of Supervisors accusing county officials of deleting election databases. The letter also questioned why there were discrepancies between certain batches of ballots and log sheets, and why broken seals were found in ballot boxes.Trump released a statement echoing Fann's letter, which also spread on social media. It read, in part: “The entire Database of Maricopa County in Arizona has been DELETED! This is illegal and the Arizona State Senate, who is leading the Forensic Audit, is up in arms. Additionally, seals were broken on the boxes that hold the votes, ballots are missing, and worse.”At a meeting Monday, county officials refuted the allegations and issued a 14-page response to Fann, calling her accusations “false, defamatory, and beneath the dignity of the Senate.” The letter, along with a separate technical memo, detailed the procedures around the vote and explained how they had been misunderstood by those behind the Senate's audit.In refuting the claim about deleted databases, the county listed a number of technical mistakes that may have been made by the firms running the audit when they configured a copy of the data and searched for the files in question. Furthermore, Megan Gilbertson, communications director for Maricopa County Elections Department, told The Associated Press that “the county backs up and archives all of its election data.”

ClaimSM-102 is an ingredient in the Moderna vaccine that is not safe for humans or for veterinary use.

The factsAs millions of Americans receive COVID-19 vaccines, posts online are falsely claiming that an ingredient listed in the Moderna vaccine is unsafe for humans and animals.One Instagram user posted a video that compares the ingredient list for the Moderna vaccine with the ingredients in a chemical solution made by the Michigan biotech company Cayman Chemical. Both products list SM-102, a lipid, as an ingredient.The Cayman product comes with a warning that it is to be used for research purposes only and contains chloroform.In fact, SM-102 — the ingredient both products have in common — is harmless to people and isn't what makes the Cayman Chemical solution dangerous. Only the Cayman product contains chloroform, a hazardous solvent.

ClaimA video shows a child shaking uncontrollably in response to the COVID-19 vaccine.

The factsA video of a child with epilepsy experiencing a seizure is being shared online to falsely imply the child is reacting to a COVID-19 vaccination.The video shows a young boy in an orange and blue shirt trembling as an adult woman soothes him, saying, “Come on, baby” and telling him to breathe. Overlaid text on the clip reads, “But they're safe right?!” and copies language about the safety of COVID-19 vaccines from the World Health Organization.In a version that amassed more than 2 million views on Facebook, a second video alongside the first shows a woman crying and shaking her head in fear. Taken together, the post falsely implies the child's physical symptoms are somehow related to the COVID-19 vaccine.But in a May 6 Instagram post, the boy's father explains that the child has epilepsy and has experienced seizures since 2009. “No, nothing to do with Covid,” the post reads. In the post, the father does claim that his son's epilepsy is related to vaccines he received as a young child. But that is not supported by scientific evidence, Dr. Paul Offit, a vaccine expert at the Children's Hospital of Philadelphia, told The Associated Press. “Vaccines do not cause epilepsy,” Offit said.One side effect of many vaccines is a fever, which can cause seizures in a small percentage of young children, Offit explained. But those seizures, known as febrile seizures, are “short-lived and do not cause permanent harm,” he said.

ClaimA photo shows Egypt projected the Palestinian flag on its Giza Pyramids during the latest war between Palestinian militants in Gaza and the Israeli military.

The factsAn internet search reveals this image was fabricated using a 2014 photo of the pyramids that did not feature the flag projection. Since fighting broke out between Israel and the Hamas militant group in Gaza on May 10, neighboring Egypt has treated wounded Palestinians and sent trucks carrying humanitarian aid and medical supplies to Gaza.However, Egypt has not shown solidarity with the Palestinians in the form of a light show on its three famed pyramids of Giza, despite a fake image suggesting as much on social media.

ClaimPresident Joe Biden was caught fake driving a Ford F-150 Lightning truck during a visit to a Ford safety testing center Tuesday. A man in the passenger seat was operating the vehicle using a second steering wheel.

The factsAn article shared thousands of times on Facebook this week falsely claimed that the president faked his Tuesday test drive of an electric Ford truck at Ford's Rouge Electric Vehicle Center in Dearborn, Michigan. “WOW! Biden Caught Fake Driving —Someone Else Is Steering Vehicle — It Was All a Stunt!” a headline on the conservative website The Gateway Pundit read.The story misrepresented videos and pictures to claim they showed a passenger in the truck was steering instead of the president. There's no truth to these claims, according to Melissa Miller, manager of government and public policy communications at Ford.“There was only one steering wheel in the vehicle the president drove yesterday,” Miller said in an email Wednesday. Photos and videos of the event show that the passenger in the vehicle, who was identified to reporters as a member of Biden's Secret Service detail, was adjusting a camera that was resting on the dashboard, not operating the car.
