Sanders does not want to participate in the debate on Feb. 4, five days before the state primary election, because he does not want to risk being denied participation in future debates, campaign manager Jeff Weaver said, according to the newspaper.

It would be sponsored by MSNBC and the New Hampshire Union Leader newspaper.
