In one sketch, set in the White House press briefing room, "SNL" cast member Aidy Bryant plays deputy White House press secretary Sarah Huckabee Sanders. A reporter asks Bryant's Sanders, "Can you just do this full time instead of him?" referring to McCarthy's Spicer, who is seen hiding in bushes outside the briefing room.
Another reporter chimes in, "I'd also like to ask that question. You are clearly articulate and charming, whereas Sean is bullish."
McCarthy's Spicer then emerges and sprays the reporter with fire extinguisher foam.
"That's right — Spicey is back, Sarah is out," shouts McCarthy's Spicer.
Later on in the sketch, McCarthy's Spicer meets with Baldwin's Trump at his New Jersey golf club, where the pair embrace and kiss.
"Sean, kiss me," says Baldwin's Trump.
"I can't. I have a wife. I took vows," says McCarthy's Spicer.
"I'm famous. It's OK," says Baldwin's Trump.
McCarthy's Spicer asks, "Is this like 'The Godfather,' where you kiss me and no one ever sees me again?"
Baldwin's Trump replies, "Yes."
