"The fact that a candidate can call for changing the date of the debate only two days before it is scheduled indicates how easy it would be for the candidates to also call for the inclusion of the leading third party and independent candidates, which would bring fresh ideas to the table on how our country can truly tackle this heavy challenge," Nader and Barr said.

"We have been notified by the Commission on Presidential Debates that we are proceeding as scheduled."
