Donald Trump's lies are largely to blame for his supporters' anger and the increasingly ugly scenes at his campaign rallies, according to Bill Maher.

"There is a lot of anger there, but can we just get to what he says? Because a lot of the reason why people are angry is because he lies, horribly, like they all do at the debates," Maher said. "Nobody checks them on it. There's that old saying, 'Dance like no one's watching.' He lies like no one is fact-checking. And no one does."

Maher detailed just some of the untruths Trump told during Thursday night's debate -- about GDP, employment levels and military spending.

HuffPost Senior Politics Editor Sam Stein agreed, revealing it was "almost impossible" to call Trump out on a single lie because he spouts 20 per minute. "You end up trying to grab over here -- and that's not even getting to Trump Steaks, which are atrocious, and he says that they're good."

Last week, Maher pointed out how frighteningly similar Trump sounds to Adolf Hitler.

Editor's note: Donald Trump is a serial liar, rampant xenophobe, racist, misogynist, birther and bully who has repeatedly pledged to ban all Muslims -- 1.6 billion members of an entire religion -- from entering the U.S.
