How Clinton and Sanders Backers Are Trying to Come Together on Party Platform

A Democratic panel is launching deliberations on the party's positions.

A panel of 15 party leaders and policy experts —- six chosen by the Clinton campaign, five from the Sanders campaign and four from party leadership -– has tried to woo Sanders supporters by scheduling multiple forums for discussion about the party’s platform, which Sanders backers are trying to push to the left over the coming weeks.

But the atmosphere here showed leaders are anxious about the possibility of disruption. A sign outside the venue banned signs and noisemakers. “When we disagree…please try to do it without being disagreeable,” Wasserman-Schultz told the room.

Some top Sanders supporters have already begun vouching for coming together. Congressman Raul Grijalva, a top Sanders backer and co-chair of the Congressional Progressive Caucus, told ABC News that Sanders should get behind Secretary Clinton.

“I’m calling for unity, yeah,” he said. “But I think that the best way to beat Trump and to win back the Senate and close the gap in the House of Representatives and win down line with offices across the country is to have a unified party."

Although Wasserman-Schultz pushed for a “fair, open and inclusive process,” but that didn’t stop Rep. Luis Gutiérrez — a Clinton campaign pick for the committee — from taking a jab at the chairwoman.

“I don't know if you would have chosen me but the only way I got here is you let other people choose,” he said.

“My hope is that in a forum like this we’ll all come together and agree,” Stuart-Freas told ABC News. “I’m not here to disrupt anything. We’re just here as a presence.”
