HBO’s Bill Maher on Friday joked that Roseanne Barr’s racist tweets were “bordering on presidential.”

Barr, a longtime friend of Maher, dominated national headlines this week after sending a racist tweet comparing former Obama adviser Valerie Jarrett to an ape.

While acknowledging that Barr will “always be [his] friend,” Maher criticized the tweets that prompted ABC to cancel Barr’s show.

“So full of racism, conspiracy theories and personal attacks,” Maher said of the tweets. “Abhorrent, bordering on presidential.”

“Now, my friend Roseanne had admitted that she had been admitted to a mental institution,” Maher added. “She has said she has multiple personalities and unfortunately, one of them is quite a racist.”

Barr apologized for the remark and announced that she was leaving Twitter, but has since tweeted other defenses of the comment and said that she “begged” ABC to save the show.

Maher also referred to President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

“This guy could tweet about the Hawaii volcano and he’d make it about him,” Maher joked. “‘I’m orange and gassy! Where’s my headline?”

Maher also criticized “snowflakes on the right” for calling for him to be fired for past jokes comparing Trump to an orangutan. Some conservatives have cited offensive comments made by left-leaning TV personalities as proof of a double standard compared to how pro-Trump talent is treated.
