The Vermont senator then touted his wins in 22 state primaries and caucuses. He said he is fighting to "transform our country," and urged people to "understand that we are in this together."

Sanders said he plans to fight for every vote in Tuesday's primary in Washington, D.C., and then vowed to bring his fight to the Democratic National Convention in July.

Still, he admitted there is a "very, very steep fight."

"But you know that what we are doing is about more than Bernie Sanders," he said in he email. "It is all of us together. It is what this movement is about. It is millions of people from coast to coast standing up and looking around them and knowing that we can do much, much better as a nation."

The email urges supporters to donate $2.70 to his campaign to help fight for a progressive future.

"The struggle continues," Sanders says at the end of the email.

Early Wednesday morning during a California rally, Sanders said he would continue to fight on in the Democratic primary and up until the convention.

“We are going to fight hard to win the primary in Washington, D.C., and then we take our fight for social, economic, racial and environmental justice to Philadelphia, Penn.,” Sanders said during the event.

Clinton held a victory rally Tuesday night, where she touted becoming the first woman to be the presumptive presidential nominee for a major party. Clinton also reached out to Sanders's supporters during the rally in an attempt to unify the party.
