Rep. Mary Miller, currently serving in the U.S. Congress for Illinois’ 15th district, has been vocal on social media about various issues. On June 20, 2025, she expressed her stance on gender and public facilities. "A biological woman should not have to share a bathroom or locker room with a biological man. Why is this so hard for the Left to understand??" This statement reflects ongoing debates over transgender rights and access to gendered spaces.
Later that day, Miller reiterated her views on gender identity by stating "Men can never be women. Period." She noted that the Secretary of Defense shares this understanding but criticized some of her colleagues for not agreeing, calling it "embarrassing."
On June 21, 2025, Miller shifted focus to environmental topics by praising carbon dioxide's role in ecology and agriculture. She tweeted: "CO₂: The Miracle Molecule It greens the Earth, fuels plant life, and supports thriving agriculture." She urged followers not to heed what she described as "Green misinformation" from political opponents.
Born in Oak Park, Illinois in 1959 and residing in Oakland, Mary Miller graduated with a BA from Eastern Illinois University before taking office in 2021 after succeeding John Shimkus.
