In an effort to unite New York Democrats, Governor Andrew Cuomo made a surprise appearance with Bernie Sanders at the state delegation breakfast. Zack Fink filed the following report.

With New York's delegation divided over support for Bernie Sanders and Hillary Clinton, Governor Andrew Cuomo made a peace offering, showing up on the second day of the convention with Bernie Sanders at his side in a call for unity.

Sanders lost to Clinton in the New York primary but still got 42 percent of the vote. He reminded all of the Democrats that their common goal is beating Donald Trump.

"We must defeat the worst Republican presidential candidate in the modern history of this country," Sanders said.

Cuomo spoke to us exclusively about the election and what is at stake.

"Not to underestimate Donald Trump and not to underestimate his campaign," Cuomo said. "He has felt and is using the fear and anxiety that is out there. And there is fear and anxiety out there."

We asked Cuomo about the leaked emails that led to the resignation of DNC Chair Debbie Wasserman Schultz the night before the convention began.

"It was an unfortunate start. But I also think it's a walnut in the batter of eternity," Cuomo said.

"Walnut in the batter of eternity" is a borrowed phrase from Cuomo's father, former Governor Mario Cuomo, who used it in 1985 to describe the demise of the Westway construction project on Manhattan's West Side. The metaphor means it's something that Cuomo says people will quickly forget.

Cuomo's day was not without some hiccups, like when a pro-Palestinian demonstrator interrupted his speech in front of the party's LGBT caucus.

But all in all, the governor believes he succeeded in bringing the party together, even though he still doesn't know when he will speak at the convention.

"Selfishly, the best day at a convention to speak is the last day, Thursday. Because Thursday is the most important day. Of course, it's the day that everyone wants to speak, and they can't work that out," Cuomo said.

New York City Mayor Bill de Blasio is also in Philadelphia had a number of meetings, including with Bill Lipton of the Working Families Party. He also had a private meeting with Bernie Sanders. We're told the meeting lasted about 45 minutes and they spoke about the future of progressive politics.
