No surprise celebrity cameos were required this time. The opening sketch of this weekend’s “Saturday Night Live,” hosted by Kristen Stewart, gave the spotlight to one of the show’s own cast members — in this case, Kate McKinnon, in her recurring role as Senator Elizabeth Warren. The sketch found her at a 2020 presidential campaign event in Iowa after proposing a $20.5 trillion health care plan.

First, McKinnon had a few general remarks for her crowd. “Look at me,” she said. “I am in my natural habitat: a public school on a weekend. And I just housed a Nature Valley bar in the hallway, so I am jacked up and ready to pipe off.”

She offered her condolences to Beto O’Rourke, who announced that he was dropping out of the presidential race. “Thank you so much for running a great campaign and sticking around long enough to call me punitive,” McKinnon said. “I was so badass. Let me know how my dust tastes, all right?”

She also offered a tongue-in-cheek encouragement to President Trump, who recently said he was changing his primary residence from New York to Florida.
