Sanders and Chairman Perez will stop in several states, including many conservative ones such as Arizona, Montana and Utah, to tap into the swell of Democratic grassroots support following the 2016 presidential election.
The objective of their road trip, dubbed the "Come Together And Fight Back Tour", is to shore up a badly fractured Democratic Party and present some semblance of a united opposition to the Trump administration.
Former presidential candidate Sen. What we have to do as Democrats is articulate very clearly that Donald Trump's vision for America is a vision for the top 1 percent of 1 percent.
Sanders told the crowd that was why he would soon be introducing legislation calling for a single payer Medicare-style health care system.
Sanders and Perez are seeking to jumpstart grassroots opposition to Republican President Donald Trump by focusing on such issues as raising the minimum wage and making public colleges and universities tuition-free. Some in the crowd also booed the first mention of the Democratic National Committee.

The Labour MP for Middlesborough South said "irreconcilable differences" with the party's leadership had led to his decision. An early election would therefore be the fourth big vote in four years after the general election of 2015.
Despite beating Sen. Sanders' endorsement for chair of the DNC, Keith Ellison, Beus stated Democrats are still ready to unite behind the party. "Here in ME we have got to stand together against all efforts to roll back the minimum wage legislation passed by the people of the state", he said. "It is not acceptable to you that we remain the only major country on earth not to guarantee health care", he said.
Sanders, an independent who caucuses with the Democrats, was enormously popular in Maine Democratic circles a year ago, winning the party caucuses over Clinton after huge crowds of supporters turned out in Portland and other towns. "We're seeing a lot more people in general getting involved in the political process and I think that is a good thing". Sanders, for instance, said the DNC should have put more resources into the Kansas special election last week, where Republican Ron Estes defeated his Democratic opponent James Thompson by 6 points.
Sanders didn't draw almost as big an audience as President Donald Trump did when he came to town for a rally last month, but his message of unity was well-received Tuesday at the Louisville Palace.
"We have got to start paying attention to the needs back home", Sanders said.
Among the emails released on Friday were several embarrassing messages that suggest the committee's chairwoman, Representative Debbie Wasserman Schultz of Florida, and other officials favored Hillary Clinton over Mr. Sanders - a claim the senator made repeatedly during the primaries. "That offended people when they went to vote".
