Stein said she also intends to pursue recounts in Pennsylvania and Michigan, though she also stated on Twitter that she would "do a recount in any state where the deadline has not passed."
Stein's campaign is trying to raise as much as $7 million for the effort online — and it had garnered more than $6 million as of Saturday evening.

Stein also took some shots at Clinton's interest in the election recount, tweeting:
"Why would Hillary Clinton — who conceded the election to Donald Trump — want #Recount2016? You cannot be on-again, off-again about democracy."
Later in the day, Trump practically offered his support for the recount, providing a seemingly baseless allegation that he would have won the popular vote "if you deduct the millions of people who voted illegally."
It was unclear where he got that notion. Voting illegally is difficult, as Trump illustrated in a 2004 video in which he was turned away from three voting locations.
The president-elect then said he could have had an easier campaign had he pursued the popular vote instead of the Electoral College. According to his Twitter account, the future commander-in-chief said he would have only had to campaign in three or four states instead of the numerous states he visited.
In the past, Trump has come out against the Electoral College. Previously, on Twitter of course, he called the institution "a disaster for democracy." He also told Mitt Romney supporters via tweet in 2012 to "fight like hell" after Romney's loss, as he incorrectly believed the Electoral College had allowed President Obama to win.
President Obama won both the popular vote and the Electoral College by large margins in 2008 and 2012.
Donald Trump's top aides on Sunday also denounced the recount effort.
"It is a total and complete hypocritical joke that the group of people that thought that they were nervous about President-elect Trump not conceding are the people that are conducting recounts in states where we won by over 68,000 votes," said incoming Trump Chief of Staff Reince Priebus on "Fox News Sunday."
Former campaign manager Kellyanne Conway also slammed the recount effort on CNN's "State of the Union," where she referenced the backlash over Trump's refusal to say he'd accept the election results during the third general election debate as evidence of hypocrisy on the part of Democrats now supporting the recount.
Multiple media analysts have opined that president-elect might be using his Twitter account to distract from more serious news, such as the New York Times investigation into Trump's potential conflicts of interest around the world.
