Lady Gaga, Pink and Sia are taking to social media to encourage fans to sign a petition that will deny Donald Trump presidency and award the election to Hillary Clinton. The petition would prevent Trump from assuming the presidency in January.

The petition already has 4.3 million signatures and counting, and is requesting that the electors of the Electoral College reject the way that their states voted this upcoming December (Dec. 19) and vote for Hillary Clinton instead.

It states that, “Mr. Trump is unfit to serve. His scapegoating of so many Americans, and his impulsivity, bullying, lying, admitted history of sexual assault and utter lack of experience make him a danger to the Republic.”

The petition further argues that although Trump won the electoral vote, Clinton held the expected victory of the popular vote by upwards of 2 million and 1.5 percentage points. It goes on to state that there is a possibility she can get it, despite the obstacles.

“If you feel scared about the current state of American politics and Whitehouse sign this petition,” Gaga wrote on Twitter, enclosing a link with the post.

Pink, Sia, Laverne Cox and model Gigi Hadad followed suit.
