Donald Trump tweeted that Saturday Night Live is “unwatchable” and “totally biased,” after Alec Baldwin impersonated him in a cold open sketch mocking his tweets.

Saturday’s episode featured Baldwin as the president-elect constantly distracted by his Twitter feed during a national security briefing. The sketch opened in a classroom, where a high school student named Seth was retweeted by Trump—recalling Trump’s real retweet of a 16-year-old named Seth, who attacked CNN over its coverage of Trump’s false claim that millions of people voted illegally.

In an attempt to defend her boss, Kate McKinnon’s Kellyanne Conway said Trump tweets so frequently “to distract the media from his business conflicts and all the very scary people in his cabinet.”

Trump disagreed that he could be so tricky.

“Actually, that’s not why I do it,” he said “I do it because my brain is bad.”

The sketch continued from there, as Trump retweeted random people while aides tried to deliver security briefings.

Trump’s critique of the episode—his second over the past two episodes—drew a response from Baldwin asking the president-elect to release his tax returns.
