(CNN) Democratic Rep. Annie Kuster of New Hampshire has endorsed Pete Buttigieg for president, giving the former mayor a significant endorsement weeks before her state's first-in-the-nation primary.

Kuster, who will also be a co-chair of Buttigieg's campaign, is the first member of New Hampshire's congressional delegation to endorse in the 2020 Democratic primary.

"With our country so consumed by division, @PeteButtigieg is the leader who can finally turn the page on the Trump presidency and bring our nation together," Kuster tweeted Wednesday. "He has the courage to break from the past to lead us to a better future -- I'm excited to endorse him to be our next president."

The congresswoman will officially back the former South Bend, Indiana, mayor at an event in Concord, New Hampshire, on Friday.

Buttigieg praised Kuster in a statement released Wednesday.
