(WB) Award-winning singer and songwriter Lady Gaga is set to appear with Joe Biden at a get-out-the-vote event Monday night in Pittsburgh, Penn. as the 2020 presidential election draws to close, the Biden campaign announced Sunday.

Details about the event were scarce in the announcement, but the campaign indicated LGBT icon Lady Gaga would join Biden that evening at a drive-in event, which is set to take place in a state Trump won in 2016 and deemed a battleground for 2020.

The event is set to happen Monday after a canvass kickoff event with Biden in Beaver County, Pa. and an earlier drive-in event for the Black community in Pittsburgh. Also set to appear at the event with Lady Gaga is Dr. Jill Biden.

Meanwhile, singer John Legend is set to join Kamala Harris and Doug Emhoff on Monday evening for an election-night drive-in event in Philadelphia.

Tim Murtaugh, a Trump campaign spokesperson, slammed Biden in a statement for campaigning with Lady Gaga, calling her an “anti-fracking activist” based on her support for Yoko Ono’s anti-fracking initiative in New York in 2012.

“Nothing exposes Joe Biden’s disdain for the forgotten working men and women of Pennsylvania like campaigning with anti-fracking activist Lady Gaga,” Murtaugh said. “This desperate effort to drum up enthusiasm for his lackluster candidacy is actually a sharp stick in the eye for 600,000 Pennsylvanians who work in the fracking industry.”

Lady Gaga responded with a tweet scoffing at the criticism, marking up the copy of the statement in an image with the text asking “What is a fracking? Keep your jobs PA.”

“HEY TIM HEY @realDonaldTrump SO HAPPY IM GLAD TO BE LIVING RENT FREE in your HEAD. #BidenHarris,” Lady Gaga tweeted.
