During a Friday night interview with Nebraska Senator Ben Sasse on Real Time With Bill Maher, the show's eponymous host caused a stir when he said the N-word. 

Sasse invited Maher to his home state to "work in the fields with us." Maher answered, "Work in the fields? Senator, I'm a house nigga."

Maher seemed to delight in his audience's discomfort, and followed up by saying, "It's a joke." Unsurprisingly, there were plenty of people who did not find the TV host's use of the slur funny.

Others pointed out that Maher has made racially insensitive comments before.

The Real Time host is no stranger to controversy. He hosted alt-right posterboy Milo Yiannopoulos on his show back in February. In addition, he has a long history of insulting Islam, as you can see in the video below, compiled by the Grayzone Project.
