Boston Mayor Michelle Wu endorsed fellow progressive Democrat U.S. Sen. Ed Markey in his reelection bid, as the 79-year-old seeks a third Senate term.

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.”

A potentially historic nor’easter is battering Massachusetts Monday morning, closing schools, threatening power outages and making travel dangerous.

Much of the state was expected to get at least a foot of snow, and more is possible in Boston — in southeastern Massachusetts, some places were forecast to get more than two feet.

Connor Hellebuyck delivered a goaltending performance for the ages, but every netminder needs a little help at times.

And in the third period of the USA’s heart-stopping 2-1 overtime win over the Canadians in Sunday’s gold medal game, the UMass Lowell product turned to another Hockey East product, Bruins defenseman and former Boston University Terrier Charlie McAvoy, for some game-saving assistance.

The Canadians threw everything at Hellebuyck with the score tied 1-1. A go-ahead goal for Canada seemed inevitable. At one juncture, former Bruin Brad Marchand threw the puck toward the net. In a scramble, Tom Wilson got the puck and he had Hellebuyck down and out. He flipped it over the netminder, but McAvoy was there on the goal line to block it with his chest and then scoop it with both hands away from danger without closing either one on the puck.

It was a huge moment in the game, which was eventually won on Jack Hughes’ golden goal less than two minutes into overtime to lift the Americans to a 2-1 win and their first gold medal since 1980.

And it was quite a moment for McAvoy. The Long Beach, N.Y., native grew up in the U.S. National Team Development Program. Last year at the 4 Nations tournament, McAvoy played a monster game when the Americans beat the Canadians early in the tournament in Montreal but was sidelined for the championship game in Boston with the shoulder injury that became dangerously infected and cost him the rest of the season.

He was overcome by emotion when Hughes’ goal went in.

“I can’t wait to see the footage of what happened after we scored, because it was a complete blackout, who I was hugging, where I was going. I don’t know what happened,” McAvoy told reporters in Italy. “It was euphoria, man. I can’t even explain what I was feeling. Just pure joy.”

There were plenty of local ties to this win. Millis and Boston College product Matt Boldy scored the game’s first goal. McAvoy’s Bruins teammate Jeremy Swayman, who won a game in the tourney, also took home the gold. Wilbraham native and BC alum Bill Guerin was the GM and, in fact, took some heat when he left scorers Cole Caufield and Jason Robertson off the roster.

And behind the bench was Mike Sullivan, son of Marshfield and BU and McAvoy’s father-in-law. Sullivan went to bat for Guerin.

“The team was built with personality in mind,” said Sullivan, the former Bruins and current Rangers coach who won two Stanley Cups with Pittsburgh. “There are whiskey drinkers and milk drinkers. And we got a lot of whiskey drinkers.”
