Trump's reaction to be specific, I really think Trump has no soul. I would not have expected him to say anything, that would be okay.

But this.... in his own words:

“Rob Reiner, a tortured and struggling, but once very talented movie director and comedy star, has passed away, together with his wife, Michele,
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, sometimes referred to as TDS,”

“He was known to have driven people CRAZY by his raging obsession of President Donald J. Trump, with his obvious paranoia reaching new heights as the Trump Administration surpassed all goals and expectations of greatness, and with the Golden Age of America upon us, perhaps like never before. May Rob and Michele rest in peace!” --He posted this word for word on Truth Social

This man, if you can even call him that, is sick and filled with hate for anyone who does not idolize him.
