It was about endorsements, but probably a bit more too.
Nobody has noticed the texts. Before the discussion on the Samson/Christie meeting, a name is mentioned along with a question, "Did you speak to her?"
That name is Nancy, and I believe it is Mayor Fulop's aide, Nancy. Wildstein, my guess was to call Nancy and cancel a meeting because Mayor Fulop was not going to endorse Christie.
Fulop had lots of meetings with Christie people, most of them cancelled on the 18th of July, the same time Kelly sends Wildstein the name Nancy, followed by a phone number, and then a question later of "Did you speak to her?"
