PHILADELPHIA — In a speech that was met with excitement and lament almost simultaneously, Sen. Bernie Sanders said Monday night his supporters should be proud.

"I understand that many people here at this convention hall and across the country are disappointed," Sanders said at the Democratic National Convention. "But to all of our supporters…I hope you take pride in all of our accomplishments."

"Together we have begun a revolution to transform America and that revolution continues," he said.

The senator from Vermont told the crowd he stands by Hillary Clinton, a welcome show of support to many in the party who worried about not showing a unified front on Monday night inside the Wells Fargo Center.

Several disgruntled members of the Democratic party held rallies in Philadelphia earlier Monday, calling for Clinton to leave the race after a slew of leaked emails led to DNC Chair Debbie Wasserman Schultz saying she'd resign after the convention.

Some of the leaked emails appeared to show the DNC favored Clinton's candidacy over Sanders'. On Monday, the DNC committee issued an apology to Sanders.

"Election days come and go, but the struggle continue to create a government" that is fully representative, "that struggle continue," Sanders said.

He also reiterated that he'd be standing by Clinton , the presumptive Democratic nominee, throughout the general election.

"Let me be clear: This election has never been about Bernie Sanders, Hillary Clinton, Donald Trump , … it is not about all the things the media spends talking about," Sanders said. "This election is about the American people and the future we can create for our children and our grandchildren."

Sanders also hit on one of his campaigns main talking points: Income inequality.

"This election is about ending the grotesque level of wealth inequality in our country. It is not moral, it is not sustainable that the top 1 percent owns more than the bottom 90 percent," he said, while at the same time praising Clinton for her position on minimum wage.

"Hillary Clinton understands that if someone in this country works 40 hours a week, that person should not live in poverty," Sanders said. "She understands we need to raise the minimum wage to a living wage."

Sanders also took a shot at Trump for his opposition of raising the federal minimum wage of $7.25 per hour, or, as Sanders put it, a "starvation wage."
