U.S. Sen. Elizabeth Warren is ramping up the messaging on her track record, touting more than $50 billion in federal funding she has brought back to Massachusetts during her congressional tenure just as a Republican could soon announce a campaign against her.

Warren, a second-term Democrat from Cambridge, released a report that highlights the billions she says she has secured for projects all across Massachusetts since she took office in 2013, including for infrastructure, public safety, research, and transportation initiatives.

“Senator Warren’s record of fighting for key priorities for Massachusetts families has paid huge dividends. It has resulted in critical federal support for infrastructure and broadband, basic research, a cleaner environment, and dozens of projects to support workers, families, and communities in the commonwealth,” the report said.

Warren pointed to $350 million the Senate Energy and Water Development subcommittee included in the fiscal year 2024 appropriations bill for the Cape Cod Canal Bridges and another $372 million the Biden administration awarded to rebuild the Sagamore Bridge.

A report commissioned by Warren, U.S. Sen. Ed Markey, and U.S. Rep. Bill Keating said failure to replace the bridges would be “catastrophic,” and the current condition of the structures is “untenable.”

The analysis released Tuesday said Warren “has fought for and helped obtain funding to repair and replace key bridges that pose safety risks to drivers, pedestrians, and businesses, including the Bourne and Sagamore Bridges on Cape Cod, and four bridges in Lowell.”

But Republicans argue that Warren is vulnerable to a challenger, if the candidate is right. MassGOP Chair Amy Carnevale said Warren is “not providing leadership for people in Massachusetts.”

“I think she’s yet to be challenged by a candidate who can really present a strong difference in terms of trying to represent people in Massachusetts who are just trying to get by and make a living and deal with things like affordability in our state,” Carnevale previously told the Herald.

Cryptocurrency advocate and attorney John Deaton is “eyeing” a run against Warren, an advisor to the potential candidate said last week. Deaton, whose 2017 arrest resurfaced the same day Warren made a fundraising appeal, could announce a campaign in the coming days.

Deaton is no fan of Warren, having railed on social media against her stances on crypto. In a statement to the Herald, Deaton again went after Warren.

“Sen. Warren said she was going to the Senate to fight for the middle class, but after a decade, has accomplished nothing other than finger pointing and further dividing our country,” he said. “Meanwhile, the middle class is suffering more than ever before, and kids growing up in poverty, like I did, have little chance of escape.”

Warren has nearly $4 million in campaign cash on hand as of Dec. 31, according to federal election records, and a nearly 11 year record in Congress.

In the analysis of her work, she pointed to millions brought back to expand broadband access in Massachusetts and public transit and energy infrastructure.

That includes $100 million for the Green Line Extension, which she said “significantly reduces vehicle trips and air emissions while improving access to quick and reliable public transit service in historically underserved areas.” The extension has encountered multiple issues since it opened.

“The project is expected to support increased ridership of more than 50,000 passenger trips per day in the coming years,” the report said.
