Biden acknowledged that a number of states have yet to vote in the primary but touted support from numerous former 2020 presidential rivals who have endorsed him over the past two weeks.

"Together we're bringing this party together," the former vice president said.

Biden secured victories in Michigan, Missouri and Mississippi on Tuesday, adding to a growing list of primary wins across the country.

Idaho, North Dakota and Washington state were also voting, though those states had not been called before Biden delivered his remarks.

The former vice president’s win in Michigan marked a massive blow to Sanders, who unexpectedly won the state’s primary in 2016.

Sanders notably did not address supporters on Tuesday from Burlington, Vt., his hometown.

Tensions have run high between the two campaigns, which have represented the progressive and moderate wings of the party.

Biden and Sanders are scheduled to take part in a head-to-head debate on Sunday in Arizona.

The next contests are slated for March 17 in Florida, Arizona, Illinois and Ohio. Sanders did not win those states in 2016, and they currently appear to favor Biden.
