Boston Mayor Wu endorses 79-year-old Ed Markey’s Senate reelection bid

Wu’s endorsement comes after Markey backed her twice for mayor, and as the senator looks to hold off a challenge from U.S. Rep Seth Moulton, a 47-year-old military veteran who is seen as a more moderate Democrat.

“Senator Markey has been a longstanding partner for Boston families, standing strong on our values, and delivering results by bringing resources and solutions,” Wu said in a statement provided by Markey’s campaign. “He is a bold leader on national issues like climate, health care and economic justice, while also delivering reliable and responsive constituent services for residents every day.”

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, 41, and U.S. Rep Ayanna Pressley to introduce legislation that would make the MBTA free for all users and build on the mayor’s pilot program that waives fares for three public bus routes in Boston.

Markey said he was “deeply honored” to be endorsed by Wu, who he described as “one of the boldest and most visionary leaders in America today.”

“Michelle and I don’t just share values — we deliver results,” Markey said in a statement. “From confronting the climate crisis to protecting our immigrant communities, to expanding affordable housing and building a city where every neighborhood can thrive, she is shaping the future of Boston with urgency.”

Markey added that he and Wu would work together “to continue to fight back against Donald Trump’s chaos.”
