Zimmer also alleged that she was pressured by New Jersey Commissioner Richard Constable to reconsider the development when they were at a television special. A spokesperson for the New Jersey Department of Community Affairs called the accusation "categorically false."
Christie spokesman Reed said Zimmer had posted multiple messages of support for Christie on Twitter, even after the conversations last spring during which she says she was pressured to back the development.
To be clear I am very glad Governor Christie has been our Gov. I am not endorsing bc of Hob's non-partisan mayoral race.— Dawn Zimmer (@dawnzimmernj) August 20, 2013
Reed also pointed out multiple instances where Zimmer thanked Christie for his help in the days immediately after Hurricane Sandy.
Zimmer said the conversations happened in the spring of 2013. When asked by Kornacki why she did not come forward earlier, Zimmer said, "I probably should have come forward then. This is the hardest thing I've ever done."
