Republican mayoral candidate Hal Heiner‘s latest ad is the most critical yet of the general election. In it, Heiner accuses Democratic candidate Greg Fischer of making a backroom deal for independent Jackie Green‘s endorsement.

Green previously told multiple media outlets (WFPL included) that he would drop out of the race and endorse Fischer if Fischer promised to, if elected:

  1. Give “real power” to his proposed Office of Sustainability
  2. Let the Jackie Green for Mayor team have input on choosing that office’s leadership

Heiner has called on the two to release any e-mails they traded regarding the endorsement. Both sides have refused.

Previously, Chris Poynter with Heiner’s campaign called the Republican’s reaction “sour grapes,” and said there was no deal made, though Green will have an advisory role in creating the Office of Sustainability, if Fischer is elected.
