Mayor Bill de Blasio's relationship with Hillary Clinton's campaign is being laid bare in embarrassing private emails published by Wikileaks this week. The latest round shows Clinton's campaign manager calling de Blasio a terrorist. The mayor is responding to the document dump by downplaying any apparent discord. And he did so on a day that brought him face to face with the New York Post reporter he shut down last week. NY1's Grace Rauh filed the following report.

Mayor de Blasio's public flirtation with Bernie Sanders last year did not go over well with Hillary Clinton's camp. And Clinton's campaign manager made that clear in an email to another top campaign aide last June.

"Wow. What a terrorist," wrote Robby Mook.

"Told you," campaign spokeswoman Jennifer Palmieri fired back.

They were responding to the mayor's kind word for Sanders when de Blasio was asked if he would attend a Clinton rally.

"Robby Mook called me this morning. I informed him that I was a loyal American. And it's the heat of battle. I understand the heat of battle. People are upset," De Blasio said.

Mayor de Blasio may have thought he was playing a strategic political game last year when he held off on endorsing Clinton, despite his close ties to her and her husband. But as private emails released by Wikileaks show it put him on the outs with Clinton's campaign.

"I was not satisfied with what I was seeing from their platform and I wanted to see more. And I thought it was important for them. I thought it was important for the party. And I thought it was important for the country. And of course it was going to be the cause of friction. That's not surprising," De Blasio said.

At a voter registration news conference Thursday, the mayor also spoke somewhat philosophically about what the leaked emails mean for the way we communicate. 

"I think we've all ended up in this loquacious electronic writing culture. And it is bankrupt now," De Blasio said.

NY1 and the New York Post have sued the mayor over access to emails he exchanged with his top outside advisors, known as the Agents of the City.

"My advice to everyone right now would be talk more, write less," De Blasio said.

The mayor did call on the New York Post's bureau chief, Yoav Gonan, for a question at the event.

Last week he refused and called the paper a right-wing rag.
