CNN will host a town hall event Wednesday night with the Green Party's nominee Jill Stein and presumptive running mate Ajamu Baraka.

Stein and Baraka will discuss the party’s platform and answer questions from voters, CNN said in a news release.

As the Green Party’s 2012 presidential nominee, Stein won just 470,000 votes nationally, but she could gain additional support this year from supporters of Bernie Sanders who refuse to back Hillary Clinton as the Democratic nominee.

Some Sanders backers spurn Clinton, say they'll go Green Party

At the Democratic convention in July, Stein accused the Democratic National Committee of sabotaging the Sanders campaign, and on the first day of the convention, hundreds of pro-Sanders demonstrators marched through Center City chanting “Bernie or Jill, No Hill."

In 2000, Ralph Nader drew 2.9 million votes nationally as the Green Party's nominee and faced blame for playing the role of the spoiler who helped deliver Florida to George W. Bush in his race against Vice President Al Gore. This time around, the Green Party is aiming to get on the ballot in 47 states.

CNN hosted a Libertarian Party Town Hall on Aug. 3 with nominee Gary Johnson, a former New Mexico governor, and William Weld, a former Massachusetts governor.

The event will air at 9 p.m. ET on CNN, CNN International and CNN en Espanol and will be live-streamed online.
