Slate: “Jack Posobiec is very concerned about voter fraud. An influential MAGA voice and prominent conspiracy theorist, he’s perhaps best known for amplifying the 2016 ‘Pizzagate’ conspiracy, which culminated in a man firing a gun in a D.C. pizza restaurant.”

“In the years since, Posobiec has loudly espoused a range of debunked conspiracy theories. That includes the GOP theory—once semi-fringe and now thoroughly MAGA mainstreamed—that Democrats have won elections via millions of fraudulent votes. The Republican National Committee last fall enlisted him to speak to poll watchers about election security. Posobiec is particularly focused on Pennsylvania, repeatedly accusing the state’s Democratic officials of fraud, even spreading conspiracy theories that were followed by an RNC lawsuit.”

“The focus on voter fraud in Pennsylvania is particularly ironic because it sure looks like, and a trail of documentation suggests, that Posobiec is living in Maryland but voting in Pennsylvania. If so, that would be a violation of voting laws, experts say.”
