Donald Trump posted a mocking message on Truth Social after Rob and Michele Reiner were found stabbed to death, drawing widespread criticism following an earlier White House defense of his remarks.His post repeated the phrase TRUMP DERANGEMENT SYNDROME, described Reiner as having driven people “crazy,” and drew more than 9,300 reposts and 38,900 likes while some supporters called it tacky and heartless.The LAPD has arrested the Reiners’ son, Nick Reiner, who is held without bail as investigators probe his reported drug use and erratic behavior, and psychologists including John Jost, Daniel R. Stalder and Jay Van Bavel said the reaction reflects narcissistic projection, victim blaming and social media–fueled dehumanization.
