Boston Mayor Michelle Wu has endorsed fellow progressive Democrat U.S. Sen. Ed Markey in his reelection bid, as the 79-year-old seeks a third Senate term. Wu praised Markey's partnership with her administration and his work on key issues like climate change and public transit.

Why it matters

The endorsement from the popular Boston mayor provides a boost to the veteran senator as he faces a challenge from U.S. Rep. Seth Moulton, a 47-year-old military veteran seen as a more moderate Democrat. The race highlights generational and ideological divides within the Democratic party.

The details

Wu's endorsement comes after Markey backed her twice for mayor. Markey's campaign highlighted his partnership with the Wu administration to deliver major federal investments to Boston, such as helping to secure $472 million to replace the North Station Draw One Bridge, advancing clean energy and climate resilience efforts, and supporting improvements for Franklin Park. The senator also cited his work with Wu and U.S. Rep Ayanna Pressley to introduce legislation that would make the MBTA free for all users.
