Stressing that the Democratic National Convention will be a “stark contrast” to the Republicans' nominating event last week, Robby Mook said Sanders will be working to unite the party.

In his convention speech, Sanders will address “how we are stronger together,” Mook said, “to take on the rigged system ... and get the economy working for everyone.”

Sanders's supporters have long thought that Democratic National Committee (DNC) officials tilted the primary process in Clinton’s favor, and many feel that DNC emails leaked over the weekend validate those beliefs.

The Clinton campaign also aimed to assuage fears that there may be a rocky relationship between Sanders, who endorsed Clinton earlier this month, and the presumptive Democratic presidential nominee.

The Vermont senator “is coming to double down on that endorsement,” Mook said. “That’s not what we saw from Sen.

“Our party is coming here to unify and defeat Donald Trump,” Mook said.

He said the convention ultimately will “reflect the values of both campaigns,” referring to Clinton and Sanders.

In response to fury over the emails, DNC Chairwoman Debbie Wasserman Schultz tendered her resignation on Sunday, although she will still be gaveling in the proceedings on Monday.

The campaign swatted away questions about Wasserman Schultz serving as a potential liability by overshadowing the convention's opening, with Mook pressing that he is less concerned about "parliamentary procedure" involved in the convention.

"What matters here is the message we’re giving to voters," he said.

Team Clinton also dismissed new polling showing a post-convention bump in support for Trump.

Mook said nominees tend to receive a boost in the polls after a convention.

“I would suspend any polling analysis until after our convention,” he added, to allow voters to compare the two events.
