Hillary Clinton will appear on Saturday Night Live this weekend, a source tells PEOPLE.
A second source confirms to PEOPLE that, in order to appear on the live broadcast, Clinton turned down an invitation to speak at Saturday night’s annual dinner for the Human Rights Campaign, the country’s largest LGBT advocacy group, in Washington, D.C.
Vice President Joe Biden, who may yet be Clinton’s competition for the Democratic presidential nomination, will speak at the dinner instead.
Clinton will speak to the group on Saturday morning.
Clinton’s campaign would not confirm her top-secret appearance (in which Miley Cyrus is set to host), but she is expected to join Kate McKinnon in a skit where the former first lady will poke fun at herself, according to The New York Times.
This is not the first time Clinton, 67, has appeared on SNL, and McKinnon has said she supports Clinton for president and she finds her “so resplendent!”
McKinnon also said there’s a lot more to her impressions of this “sweetie granny from the Midwest” than just poking fun, explaining, “It’s a combination of the writers’ take on her but also this contrast between a woman so driven and hardened by her experiences … the juxtaposition.”
Clinton is prepping for the first Democratic primary debate, which will take place on Oct. 13.
