“Real Time” host Bill Maher minced no words Friday night regarding the news that Republican megadonor and billionaire philanthropist David Koch had died at age 79 following a long battle with cancer.

“F— him… I'm glad he's dead,” Maher said.

“And now, some funeral news to report. Yesterday David Koch of the zillionaire Koch brothers died .. of prostate cancer,” Maher said during his opening monologue, sparking some applause from his mostly liberal audience.

“I guess I’m going to have to re-evaluate my low opinion of prostate cancer.”

The HBO star joked that Koch's family expressed gratitude that he “lived long enough to see the Amazon catch fire” and that condolences poured in “from all the politicians he owned.”

After briefly acknowledging the “harsh words” he had for Koch and predicting condemnation, Maher doubled down on his disdain for him and his brother, Charles Koch.

“He and his brother have done more than anybody to fund climate science deniers for decades. So f— him, the Amazon is burning up, I’m glad he’s dead, and I hope the end was painful.”
