Vermont Rep. Peter Welch announced Monday he will run for Senate next year to fill the seat held by retiring Sen. Patrick Leahy.

“I’m running for the United States Senate to work for you, for Vermont, for our country, and for our imperiled democracy,” Welch, a Democrat, tweeted. In a roughly two-minute campaign announcement video, he lamented that his party’s legislative priorities including expanded voting rights, Medicare for All and the Green New Deal were being “filibustered by the Mitch McConnell Republicans in the Senate.”

It was widely anticipated that Welch would launch a bid for Leahy’s seat; as the representative for Vermont’s at-large House district since 2007, Welch is the only other member of the state’s congressional delegation besides independent Sen. Bernie Sanders.
