Green Party nominee Jill Stein has raised millions in an effort to seek a vote recount in Michigan, Pennsylvania and Wisconsin.
She met her initial fundraising goal of $2 million early Thursday but then increased her fundraising target to $4.5 million, according to CNN.
The deadline to file for a recount in Wisconsin is this Friday, while the deadlines for Michigan and Pennsylvania are both next week.
"Over the last 48-72 hours, reports have come in from experts, cyber experts, who are reporting to us some very troubling news about the possibility of security breaches in voting results across this country," Stein's campaign manager, David Cobb, said in a Facebook video.
With Hillary Clinton's popular vote lead at nearly 2 million, Stein and liberals are now pushing for an investigation into what happened on Election Day.
According to CNN, Stein launched her effort after computer scientists reportedly told the Clinton Campaign that the election may have been rigged.
Scientists at the University of Michigan Center for Computer Security and Society noted that there was a "questionable trend" of Clinton not performing as well in counties that relied on electronic voting machines.
But political statistician, Nate Silver, tweeted a link to his FiveThirtyEight website explaining why the claim "doesn't check out."
