Notable personal detailsEdward John (Ed) Markey is a Democratic U.S. senator from Massachusetts, first elected in a June 2013 special election and sworn in on July 16, 2013. He previously served in the U.S. House of Representatives from 1976 to 2013 after serving in the Massachusetts House of Representatives. He earned a B.A. from Boston College (1968) and a J.D. from Boston College Law School (1972), and served in the U.S. Army Reserve (1968–1973).
Ed Markey supports raising taxes on large corporations and the ultra‑wealthy, stronger tax enforcement of high‑income individuals and corporations, and targeted tax measures to reduce inequality while expanding tax relief for working families (for example, an expanded child tax credit). He has opposed large Republican tax‑cut packages and sponsored or joined legislation imposing higher taxes or penalties on excessive corporate/CEO pay and windfall profits.
Ed Markey supports universal health care and has endorsed Medicare for All while also sponsoring legislation to enable state-based paths to universal coverage and to expand access to Medicare and Medicaid benefits.
Supports expanded legal pathways and a pathway to citizenship, protection for DACA recipients, limits on detention and deportation, and maintaining robust access to asylum; opposes policies that restrict asylum or expand detention and mass deportation. Advocates humanitarian, rights-respecting border management and administrative relief for undocumented immigrants.
Supports codifying Roe v. Wade into federal law and protecting broad access to abortion and reproductive health care; describes abortion as essential health care and has urged legislative action (including the Women’s Health Protection Act) to protect abortion rights and oppose restrictions.
Supports aggressive, large-scale climate action including the Green New Deal framework, net-zero emissions goals, major public investments in clean energy and climate justice, and legislation to advance climate education, resilience, and decarbonization of public infrastructure. Demonstrates consistent sponsorship/co-sponsorship of bills and resolutions that prioritize rapid emissions reductions, clean energy jobs, and environmental justice.
Supports reinstating bans on assault weapons and high-capacity magazines, universal/expanded background checks, state licensing standards and red flag laws, and other significant firearm restrictions to reduce gun violence.
