"There's a f--king culture war!" Eichner said on the HBO show. "When you're dealing with someone like Trump who is ripping infants from their parents, from their mothers, this is a battle of good versus evil -- and I don't think it's oversimplifying it and that's why young people have to vote."
Maher also weighed in on the steady stream of police brutality that continues to make headlines, calling for a #MeToo movement for cops during his "New Rules" segment.
"We need to stop saying most cops are good like we know that to be true," Maher said. "I hope it's true, but I need some evidence, unlike cops."
"The bad ones, not the good ones. Problem is we don't really know what that percentage is," he continued, showing multiple clips of police beatings."That's the question I'm asking tonight -- if so many cops are good why are there so many videos of them being bad?"
"That's a lot of videos of guys who barely exist doing shit that hardly ever happens. Not to mention the Milwaukee Buck's Sterling Brown getting tased for a crime white people can't even imagine: existing while black. This is why NFL players want to take a knee –- not because they hate the Anthem."
The late-night host had some advice of what can be done. "We need a #MeToo movement for the police," Maher said. "If Garrison Keillor has to go away for putting his hand on a woman's back, perhaps we should decide what should happen when two men pin a woman down in the sand and punch her in the face."
