Jimmy Kimmel said of Trump, "That corroded brain is in charge of our lives." He then told his audience, "If you voted for that, it’s OK to reconsider. It’s perfectly fine."

"That should never happen to anybody. I don't care what your political beliefs are. That's not acceptable," Reiner said of Kirk's shooting in September

Here's a look at what Americans think of President Donald Trump amid his remarks on the killing of Rob Reiner.

Sen. Amy Klobuchar later referenced Kimmel’s comments in relation to those Trump made after the Reiners' killings, in which Trump said Rob Reiner’s death was “reportedly due to the anger he caused others through ... a mind crippling disease known as TRUMP DERANGEMENT SYNDROME.”

Jimmy Kimmel criticized Donald Trump for making "loathsome" comments about Rob Reiner following the filmmaker's death.

The image of the purported tweet made the rounds after Rob Reiner and his wife, film producer Michele Singer Reiner, were stabbed to death in their Los Angeles home on Dec. 14. Los Angeles County District Attorney Nathan Hochman subsequently announced first-degree murder charges against the couple's 32-year-old son Nick Reiner.

Meg Ryan addressed friend Rob Reiner and his wife Michele's tragic deaths. The actress, 64, wrote a moving tribute to her When Harry Met Sally director in a tearful post she shared on December 17.
