Vermont U.S. Senator Bernie Sanders will once again run for President of the United States. Sanders announced his candidacy Tuesday morning with a campaign video to Twitter and speaking with CBS.

“I’m running for president. I am asking you to join me today as part of an unprecedented and historic grassroots campaign that will begin with at least 1 million people from across the country,” the announcement tweet read.

Sanders confidently told CBS: “We’re gonna win. We are gonna also launch what I think is unprecedented in modern American history and that is a grassroots movement.”

The announcement from Bernie Sanders follows declarations from Kamala Harris and Cory Booker, who have both announced their candidacy this month. You can view the announcement from Bernie Sanders below.
