A Campbell Soup Company executive who had planned to retire next month left last week instead after sharing a conspiracy theory on Twitter about a migrant caravan in Mexico, the company said on Monday.
Campbell said the company and the executive, Kelly Johnston, the vice president of government affairs for 16 years, had agreed to âaccelerateâ his retirement after he said on Twitter last week that a foundation led by George Soros, the billionaire philanthropist and liberal activist, was the driving force behind a caravan of thousands of migrants headed toward Mexicoâs border with the United States.
Mr. Sorosâs activism has made him a lightning rod for criticism among some conservatives and right-wing activists. Last week, a pipe bomb was delivered to his house in Westchester County, N.Y. It was one of 14 explosives sent to people who are regularly disparaged by the right. The authorities have charged an outspoken supporter of President Trump with sending the bombs.
On Oct. 22, Mr. Johnston shared a Twitter post about the caravan, adding a comment in which he said: âSee those vans on the right? What you donât 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.â
Campbell Soup said in a statement on Monday that Mr. Johnston had been scheduled to leave the company in early November. âIn the last few days, the company and Mr. Johnston agreed that under the current circumstances it would be best to accelerate the timing of his departure,â the company added.
Mr. Johnstonâs last day was Thursday, the company said.
The Open Society said in a Twitter message last week: âMr. Johnston, neither Mr. Soros nor Open Society is funding this effort. We are surprised to see a @CampbellSoupCo executive spreading false stories. We do support the historic U.S. commitment to welcoming people fleeing oppression and violence in their homelands.â
Keith R. McLoughlin, Campbell Soupâs interim chief executive, wrote to Patrick Gaspard, the president of Open Society Foundations, last week to tell him that Mr. Johnstonâs remarks did not represent the companyâs position and were âinconsistent with how Campbell approaches public debate.â
âWe regret that this episode happened and has colored his service to us,â Mr. McLoughlin said in the letter, which was dated last Tuesday.
Mr. Soros founded Open Society more than 30 years ago to promote democracy and human rights. He made his fortune running a hedge fund and has donated to Democratic candidates in the United States and to liberal causes.
Mr. Soros has been a target of anger from right-wing groups and of anti-Semitic smears. Roseanne Barr, whose television show was canceled by ABC after she posted a racist message on Twitter, is among those who have spread far-right conspiracy theories about Mr. Soros, accusing him of being a Nazi and wanting to overthrow the United States government.
The conspiracy theories about Mr. Soros have been spread against a backdrop of increasing hostility toward Jews in the United States. The Anti-Defamation League said there was a 57 percent increase in anti-Semitic incidents in the United States last year compared with 2016.
On Saturday, a man who told police that he âwanted all Jews to dieâ killed 11 people in a rampage at a Pittsburgh synagogue.
Other executives and officials have run afoul of their employers over comments on social media. In one prominent instance, CBS fired a company lawyer, Hayley Geftman-Gold, last year after she said on Facebook that the victims of a mass shooting in Las Vegas were âRepublican gun totersâ who did not deserve sympathy.
