Johnson told Neil Cavuto he’s currently petitioning the Supreme Court to ask the Appeals Court to hear his case against the Commission on Presidential Debates, however, a previous dismissal was upheld in August.

Johnson says if it succeeds, the case could level the playing field for independent and third-party candidates.

He and Green Party candidate Jill Stein sued the Commission on Presidential Debates after they were excluded from the nationally televised debates.

The Commission requires candidates to average a minimum of 15 percent in five national polls in order to be invited.
