Seth Moulton and John Deaton faced off in a Massachusetts Senate debate, where each criticized incumbent Ed Markey and discussed immigration, energy and other issues. A fact-check found some claims accurate, while others needed context or were inaccurate.
In a pre-primary debate, Democratic Rep. Seth Moulton and Republican candidate John Deaton made arguments against incumbent Sen. Ed Markey, who did not attend. The fact-check examined claims about Moulton’s comments on ICE, Markey’s position on abolishing the agency, and Massachusetts and Maryland electricity prices. It found that Deaton’s account of Moulton’s 2025 vote lacked context and that his electricity comparison used an outdated Maryland figure.
The article also examined Moulton’s claim that President Donald Trump stopped an offshore wind project, reporting that the administration tried to halt the project but it resumed and was completed. It reviewed legislation Moulton cited, including the Brandon Act, the High Speed Rail Act and the Afghan Adjustment Act, and found accurate his claim about legislation creating the 988 Suicide & Crisis Lifeline.
