Bernie Sanders' longtime top aide Jeff Weaver has agreed to help Hillary Clinton's team organize voters, both Weaver and Clinton campaign manager Robby Mook told POLITICO Playbook in an exclusive interview published Wednesday.

“Like the senator I am fully behind the secretary and certainly I will make known to all the Bernie supporters around this country who know me very well -- and have received emails from me from the last year plus -- that I am certainly on fully on board as well,” Weaver said.


The announcement, which comes with Sanders' official endorsement of Clinton as the Democratic nominee, is another indication of how the Vermont senator's team will work on behalf of the former secretary of state in the general election fight against Donald Trump. Weaver will not be joining the Clinton campaign, however.

“I think the senator’s intentions is to stump quite heavily for the secretary all across the country, obviously and specifically in the battleground states. In addition to that, he’ll be campaigning for down-ballot progressive Democrats in states all across the country — whether they are battlegrounds or not in battlegrounds. I think you are going to see a lot of Senator Sanders on the stump,” Weaver told Playbook.

Calling the situation "complex," Mook said that "obviously there is a lot of detail and that really took some time to get through." Both candidates came to an understanding of how things would work after a meeting last month, Mook added.

“It was just a matter of figuring out how to dot all the i’s and cross the t’s — which did take time, but that was the most important thing in this," Mook said. "And they actually found them fairly easy after talking through a lot of different issues.”

Noting that members of Sanders' staff have been coming onto the campaign, Mook said the "most important message we have here is that there is a seat for everybody at the table and we need every voice to not only to be successful on Election Day but to get these policies enacted next year and in the years to come.”

Weaver praised Mook's efforts in bridging the divide at the end of a contentious and protracted primary battle.

“At the end of that process it’s always a little difficult to come together with the people you’ve been competing against the last so many months, but I have to say Robby really extended an olive branch and I think evidenced himself to be a fair player who wanted to make things work, who wanted to be straight up in terms of dealing with the Sanders people and who was willing to put himself in the shoes of the millions of Sanders supporters who are obviously disappointed that the senator didn’t win,” Weaver said.
