On June 25, 2017, "Welt am Sonntag" published Hersh's article "Trump's Red Line" which had been rejected by the "London Review of Books". He said there was a split between the U.S. intelligence community and president Donald Trump over the alleged 'sarin attack' at the rebel-held town of Khan Shaykhun in Idlib on April 4, 2017: ″Trump issued the order despite having been warned by the U.S. intelligence community that it had found no evidence that the Syrians had used a chemical weapon.″ Bellingcat accused Hersh of sloppy journalism: "Hersh based his case on a tiny number of anonymous sources, presented no other evidence to support his case, and ignored or dismissed evidence that countered the alternative narrative he was trying to build."
