Steven J. Milloy (born 1959) is an American lawyer, lobbyist, author, and former Fox News commentator known for his skepticism toward mainstream environmental and public health science. He founded JunkScience.com in the late 1990s, a website that critiques what he terms 'junk science,' particularly on issues like climate change, second-hand smoke, and chemical regulations. Milloy has close financial and organizational ties to industries such as tobacco and fossil fuels, including serving as executive director of The Advancement of Sound Science Coalition (TASSC), a Philip Morris-funded group aimed at questioning the health risks of cigarette smoke. He has worked as a consultant for oil and coal companies, including as director of external policy and strategy at Murray Energy Corp from 2013 to 2015, and joined the board of The Heartland Institute in 2020. Milloy served on the Trump administration's EPA transition team and has authored books like 'Junk Science Judo: Self-Defense Against Health Scares and Scams' (2001), 'Green Hell: How Environmentalists Plan to Control Your Life and What You Can Do to Stop Them' (2009), and 'Scare Pollution: Why and How to Fix the EPA' (2016), promoting deregulation and criticizing environmental activism. His career spans public affairs consulting, securities regulation, and media commentary, with over 500 published articles and columns, including a 'Junk Science' column for FoxNews.com from 2000 to 2009. Trained in natural sciences, biostatistics, law, and securities regulation, he has worked as an attorney for the U.S. Securities and Exchange Commission, a broker-dealer, and a coal company executive. His efforts have drawn significant criticism for undermining scientific consensus; for instance, he has disputed climate change science and the dangers of second-hand smoke, often aligning with industry interests like the American Petroleum Institute and Monsanto. Milloy has testified before Congress on risk assessment and Superfund issues and remains active as a senior policy fellow at the Energy & Environment Legal Institute, continuing to influence conservative policy circles through writings and appearances on outlets like OANN.
