Senator Mary Landrieu served in the United States Senate for three terms, from 1997-2015. During her 18 years in the Senate, she chaired the Senate Energy and Natural Resources Committee, the Small Business and Entrepreneurship Committee, the Homeland Security Appropriations Committee, and was the first Democratic woman to serve on the Armed Services Committee. She is credited with the passage of several important pieces of legislation: most notably, the landmark Gulf of Mexico Energy Security Act (GOMESA); the Israel American Energy Alliance; and the Resources and Ecosystems Sustainability, Tourist Opportunities and Revived Economies of the Gulf Coast States Act (RESTORE Act) – the single largest environmental investment in the Gulf Coast in US history.

During her time in the Senate, Landrieu was known for her bipartisan approach to addressing national challenges and for her passionate advocacy for her home state of Louisiana, particularly in the aftermaths of Hurricanes Katrina and Rita.

Prior to serving in the Senate, she was elected twice to the Louisiana State Legislature from 1979 – 1987. For eight years, she successfully championed causes related to women and children, flood protection, and education reform. In 1987, she was elected State Treasurer and served with distinction for two terms. Strong fiscal management, pension fund diversification, debt limitation, and the creation of the first-ever municipal investment fund (now valued at over $2 billion) are some of her noteworthy accomplishments.

Since leaving the Senate, Landrieu served on the Board of Directors for CenturyLink (Lumen) (November 2015 - May 2020) and Tyler Technologies (January 2020 – February 2024). She currently serves on the Board of Directors for Evergy. She has been a leader in the public-school reform movement for decades and is a co-founder of the Congressional Coalition on Adoption Institute (CCAI), which represents over 150 Members of Congress who work on bipartisan policies and funding initiatives to support the notion that every child has the right to a safe, stable, and nurturing family. In addition, Landrieu serves on the board of Resources for the Future, and on the National Academy of Sciences’ Gulf Research Program Advisory Board.

She earned her BS degree from Louisiana State University and is married to Frank Snellings, an attorney and real estate broker. They reside in Washington, DC, and have two grown children and one grandchild.
