Kurt Eichenwald, a journalist for Newsweek who has been reporting aggressively on Republican presidential nominee Donald Trump, says supporters of Trump have started harassing him online by sending him videos that trigger seizures. Eichenwald, who has epilepsy, says a Trump supporter named Mike tweeted a video at him containing Pepe the Frog, a logo that has been deemed a racist signifier. “The video was some sort of strobe light, with flashing circles and images of Pepe flying toward the screen,” Eichenwald wrote. “It’s what’s called epileptogenic—something that triggers seizures. Fortunately, since I was standing, I simply dropped my iPad to the ground the second I realized what Mike had done.” Eichenwald detailed the additional abuse he’s received online, including death threats. “The deplorables are real. The deplorables are dangerous,” he concludes.
