Green Party candidate Jill Stein was expected Monday to hold a press conference in front of Trump Tower in New York City to push for vote recounts in three states – Pennsylvania, Michigan and Wisconsin – and challenge President-elect Donald Trump’s interference in the process, according to a press release from her website.

In Wisconsin, a vote recount kicked off last week. In Michigan, U.S. District Judge Mark Goldsmith issued an order for a recount of votes to begin at noon, the Associated Press reported Monday. Trump has attempted to block Stein’s recounts in Michigan and in Pennsylvania by filing lawsuits, The Hill reported Sunday.

Trump took to Twitter Sunday to counter Stein’s vote recount efforts, calling the push for recounts a “scam.” “The Green Party just dropped its recount suit in Pennsylvania and is losing votes in Wisconsin recount. Just a Stein scam to raise money!” Trump wrote.

Stein’s “Rally for the Recount” conference was slated to begin at 10 a.m. EST in front of Trump Tower on the northeast corner of 5th Avenue, and W. 56th Street in New York. News networks like CNN were expected to live stream the event.

Stein has raised a reported $7 million to assist in the voting recounts, according to her Facebook page.

“We won’t stand down as Donald Trump and his allies seek to frivolously obstruct the legal processes set up to ensure we have a voting system we can trust and that all votes have been counted,” Stein had said in a statement on the event’s Facebook page.

Stein is seeking recounts in Michigan, Wisconsin and Pennsylvania, states that have voted Democratic in recent presidential elections before flipping for Trump in 2016. If the recounts show Clinton won instead, she would have enough votes to win the Electoral College and the White House. Clinton already has more popular votes than Trump. Stein has said she isn't trying to put Clinton in the White House, but wants an overview of the integrity of voting systems.
