Green Party presidential nominee Jill Stein on Monday told the Wisconsin Elections Commission that she would sue unless the state conducted its recount by hand.

Unless she wins the case in Dane County Circuit Court, officials in all of Wisconsin’s 72 counties could decide whether they want to count election ballots manually or by machine, the Milwaukee Journal Sentinel reports. Either way, Wisconsin is set to verify its results from November 8, when President-elect Donald Trump won the state with 47.9 percent to Democratic rival Hillary Clinton’s 46.9 percent.

State officials said they expect the recount to uphold Trump’s win—but Stein’s efforts have highlighted widespread voter outrage at the election results. The Green Party candidate initiated the recount process last week after handily raising more than $6.3 million to fund the effort.

Clinton’s campaign also indicated over the weekend that it would join in the recount process in Wisconsin, as well as any potential recounts in Pennsylvania and Michigan, key battleground states where Clinton lost.

Stein filed a lawsuit Monday to force a recount in Pennsylvania and said she plans to request one in Michigan on Wednesday. Although Michigan officially certified its results on Monday, a recount may still take place there.

“We must recount the votes so we can build trust in our election system,” Stein said in a statement. “We need to verify the vote in this and every election so that Americans of all parties can be sure we have a fair, secure, and accurate voting system.”
