The endorsement from the potential 2016 presidential candidate was announced Friday by Moulton’s campaign. It comes as a new WBUR poll has Moulton up eight points against Republican opponent Richard Tisei in the race to succeed Rep. John Tierney (D).

Moulton defeated Tierney, a nine-term incumbent, earlier this month in the Democratic primary. His challenge was boosted by endorsements, including the first by retired Army Gen. Stanley McChrystal, the former top U.S. commander in Afghanistan. Warren originally backed Tierney in the primary.

The Massachusetts district leans Democratic, and the party now believes it has a better chance of holding on to it with Moulton on the ticket instead of Tierney. The Democratic Congressional Campaign Committee last week added Moulton to its list of top-tier candidates.

Moulton, who served four tours in Iraq, released an ad on Thursday that said he opposes sending troops back into the Middle East, as the U.S. expands airstrikes against the Islamic State in Iraq and Syria.

Warren last week voted against authorizing President Obama to train and equip moderate Syrian rebels in the fight against ISIS. The measure, though, passed with bipartisan support in both chambers.

The vote highlighted her anti-war credentials and comes as national security issues gain attention ahead of November’s midterms.
