Notable personal detailsDaniel Arrigg Koh is an American politician and Democratic candidate for U.S. House in Massachusetts’s 6th congressional district (2026). He previously served in senior roles in the Biden-Harris White House, including deputy director of the White House Office of Intergovernmental Affairs, and was chief of staff to U.S. Labor Secretary Marty Walsh. Koh also served as an elected member of the Andover, Massachusetts Select Board and previously ran for Congress in Massachusetts’s 3rd district in 2018.
Supports expanding access to health coverage, including universal coverage goals and preservation/strengthening of the Affordable Care Act with measures like a public option to broaden access and lower costs.
Dan Koh emphasizes his family’s immigrant background and frames immigrants as part of the American story, but I could not find a clear, detailed policy platform or concrete proposals on immigration or border enforcement on his campaign site or in major news coverage. Public statements available emphasize welcoming immigrant roots and sympathy for immigrants rather than specific policy prescriptions.
Supports clean energy investment and job creation and has worked on implementing federal infrastructure and clean energy programs; as an Andover Select Board member he helped secure clean energy choices for town residents. Positions emphasize building clean energy jobs and infrastructure while accepting a role for government-led investment.
Supports stronger background checks, an assault-weapons ban, and other common-sense gun reforms while advocating measures to improve public safety. Positions emphasize regulating firearms to reduce gun violence alongside broader public-safety initiatives.
Dan Koh is in the news as a Democratic candidate in the crowded Massachusetts 6th District race. Recent coverage says he has been using "red boxing," a tactic that signals to super PACs how to help a campaign without direct coordination. He is also being mentioned as leaning on a Joe Biden endorsement in the primary, while the field has narrowed after another candidate dropped out and Koh continues to raise significant funds.
