Former Secretary of the U.S. Senate Kelly Johnston on Monday spread a conspiracy theory alleging that philanthropist George Soros’ company Open Society “planned” the caravan of migrants heading to the border—including “where they defecate”—according to a tweet from New York Times reporter Kenneth Vogel. On Monday night, Johnston, who now works as the vice president of government affairs for Campbell Soup, reportedly tweeted a photo of the caravan alongside the caption: “See those vans on the right? What you don’t see are the troop carriers and the rail cars taking them north. @OpenSociety planned and is executing this, including where they defecate. And they have an army of American immigration lawyers waiting at the border.” There is no evidence to support any of Johnston’s claims. Campbell Soup denied responsibility for Johnston’s comments, telling Vogel that “The opinions Mr. Johnston expresses on Twitter are his individual views & do not represent the position of @CampbellSoupCo.” Johnston has since deleted his Twitter account.
