A former congressional candidate is calling for Erie County Democratic Committee Chairman Jeremy Zellner to step down.

Nate McMurray started a change.org petition, saying Zellner has too much power. The former Grand Island town supervisor accuses Zellner of using party resources and his role as chair to attach progressive candidates.

In a statement, Zellner says, in part, "Nate McMurray requested and received our endorsement in each of his three losing bids in the 27th Congressional District."

He goes on to say that McMurray is entitled to his opinion and, "Mr. McMurray’s words and actions are those of a disgruntled, failed candidate and I will consider them on that basis."
