Billionaire investor George Soros has committed $5 million to aid to fight voter ID laws and other legislation in several key states that Democrats argue keeps voters away from the polls.

Attorney Marc Elias, who also represents Hillary Clinton's presidential campaign, talked with Soros in January 2014 about supporting planned federal lawsuits for that year and the 2016 election aimed at overturning voter ID laws, according to the New York Times.

"We hope to see these unfair laws, which often disproportionately affect the most vulnerable in our society, repealed," Soros told the Times.

The Hungarian-born billionaire, a generous donor to liberal causes, is currently writing lawsuits in Ohio, Wisconsin and North Carolina.

Liberals have long alleged voter ID laws discourage minorities from voting, a charge Clinton repeated in a speech Thursday. Republicans counter that the laws are modest protections against voter fraud. The Supreme Court ruled in 2008 that states could require photo identification prior to voting.
