"Saturday Night Live" just bid farewell to one of its most popular political figures.

With the news that Attorney General Jeff Sessions was fired Wednesday, Kate McKinnon was forced to retire her quirky impersonation of the Alabama Republican during Saturday night's cold open.

The episode opened with press secretary Sarah Huckabee Sanders (Aidy Bryant) asking Sessions (McKinnon) to clear out his desk at the White House. Sessions proceeded to wistfully pack up his belongings, including a copy of the Bible ("I justified a lot of things with this book") and a Confederate flag mug reading "It's not about hatred, it's about heritage," with a smaller mug inside that said, "J.K., it is about hatred."

Donald Jr. (Mikey Day) and Eric Trump (Alex Moffat) awkwardly paid their respects to the conservative politician, as did Vice President Mike Pence (Beck Bennett). "I don't understand what I did wrong," Sessions complains to the latter. "I put kids in cages, I said no to the gays — what more did y'all want?"

After crooning a tender rendition of Adele's "Someone Like You" to a portrait of Alec Baldwin as President Donald Trump, Robert De Niro made a surprise appearance as special counsel Robert Mueller, who has investigated Russia's interference in the 2016 presidential election. Sessions' replacement, Acting Attorney Matthew Whitaker, has been critical of Mueller's investigation.

Mueller assured Sessions that he helped in the investigation "more than you'll ever know," before leaving him with a parting gift.

"You know in 'Harry Potter' when an elf gets a piece of clothing and it sets him free?" Mueller said. "This is for you."

"A piece of toilet paper from the bottom of Trump's shoe?" Sessions replied. "I'll treasure this."
