Gary Johnson, the Libertarian Party's nominee for president, has made no secret of his desire to be onstage with Republican Donald Trump and Democrat Hillary Clinton in the upcoming presidential debates.

Our America Initiative, an arm of the Libertarian Party, filed a lawsuit in September against the Commission on Presidential Debates, challenging its “15 percent threshold.” This threshold is reached when a candidate has the "support of at least 15 percent of the national electorate as determined by five selected national public opinion polling organizations." Third parties have been included in national presidential debates only twice.

The legal action, which includes the Green Party in its plea, appears to be stalled. Instead of the 15 percent threshold, the lawsuit reportedly “seeks to establish as the qualifying standard for debate inclusion getting on enough state ballots to have a mathematical possibility of winning the election.” Johnson supporters worry that if the issue is not settled by August, the Libertarian Party will have run out of time.

Green Party nominee Jill Stein has repeatedly called for inclusion in the debates, but also hasn’t turned down the idea of debating Johnson in a separate, third-party faceoff. Asked in an interview with Cenk Uygur of "The Young Turks" if she would debate Johnson on the show, Stein responded, “It’s a deal!”

It’s unclear whether Johnson will take up the challenge. Days after Stein’s comment, he spoke with the organization No More 2 Party System. Johnson first asserted that any candidate with the mathematical chance of winning a majority of votes in the Electoral College should be onstage for the presidential debates.

Asked whether he would debate Stein, Johnson first said no, thinking the interviewer meant that the debate would take place that same day. Then, told about Uygur’s offer, Johnson seemed perplexed. “Are you the publicist for Jill Stein?” he asked.

Johnson also rebuffed criticism of his vice presidential pick, William Weld, who, the interviewer said, has reportedly expressed support for Clinton.
