Green Party presidential candidate Jill Stein is scheduled to hold a campaign rally Saturday in Birmingham, her campaign said Thursday.

Stein, a physician and activist, is set to address supporters at the Birmingham-Jefferson Convention Complex's South Meeting Hall at 5 p.m. Saturday, focusing on "her vision for America and the role of third parties in America," according to an email from the Alabama Green Party.

Among the party's major issues are climate change, social justice and a dovish foreign policy. Alabama is among the 44 states where Stein will appear on the ballot.

Stein was unable to participate in the presidential debate earlier this week between Donald Trump and Hillary Clinton because she did not meet the 15 percent polling threshold required to be included.

In a statement, Stein disagreed with the decision.

"What I am really hoping to accomplish is what the American people are hoping to accomplish, which is to open up the debates so we have a fair and inclusive debate at a time where the American people rejected the two establishment candidates at record levels, they have a right not only to vote -- they have a right to know who we can vote for," she said.

Stein was also the party's nominee in 2012 and is one of two major third-party candidates in the 2016 election along with former New Mexico Gov. Gary Johnson, who is the nominee from the Libertarian Party.
