U.S. President Donald Trump has sparked fresh outrage after doubling down on his attacks against Hollywood filmmaker Rob Reiner, following the tragic killing of Reiner and his wife, Michele Singer Reiner.

The couple were found dead on Sunday afternoon at their $13.5 million Los Angeles mansion after an alleged altercation with their son, Nick Reiner. Authorities confirmed that both victims had their throats slit, and their son has since been arrested and charged with murder.

Despite the circumstances surrounding the deaths, President Trump appeared to link the tragedy to what he described as Reiner’s long-standing criticism of him, blaming it on what he called “Trump Derangement Syndrome” (TDS) — a term often used by conservatives to describe intense opposition to the former president.

In a post shared online, Trump referred to Reiner as a “once very talented movie director and comedy star,” but claimed he died “reportedly due to the anger he caused others through his massive, unyielding, and incurable affliction with a mind-crippling disease known as Trump Derangement Syndrome.”

Trump further alleged that Reiner’s “raging obsession” with him had driven people “crazy,” adding that his criticism intensified as the Trump administration “surpassed all goals and expectations of greatness.”

The remarks drew swift backlash from Hollywood figures and political opponents, with many condemning the comments as insensitive and inappropriate in the wake of a family tragedy.

However, Trump showed no sign of retreating. When questioned by a reporter in the Oval Office about his comments, he stood by them.

“Well, I wasn’t a fan of his at all. He was a deranged person, as far as Trump was concerned,” the president said. “I think he hurt himself career-wise. He became like a deranged person with Trump Derangement Syndrome. I thought he was very bad for our country.”

Trump also accused the late director of promoting the so-called “Russia hoax” — allegations that Trump was compromised by Russia during his first term — claims he has consistently denied.

The comments continue to fuel debate online, with critics accusing the president of politicising a personal tragedy, while supporters argue he was simply restating his long-held views.
