Mary Loretta Landrieu ( ;AP News Pronunciation Guide born November 23, 1955) is an American entrepreneur and politician who served as a United States senator from Louisiana from 1997 to 2015. A member of the Democratic Party, Landrieu served as the Louisiana State Treasurer from 1988 to 1996, and in the Louisiana House of Representatives from 1980 to 1988.
Landrieu came to national attention in the wake of Hurricane Katrina in 2005 after she publicly criticized the federal response to the natural disaster. Her opposition to the public option played a major role in the crafting of the 2010 Affordable Care Act, since she did not agree to support it until additional concessions were granted to support Louisiana's Medicaid system. In 2011, she became a cardinal (chair) of the Senate's Homeland Security Appropriations Subcommittee. She chaired the Senate Committee on Small Business and Entrepreneurship from 2009 to 2014, and chaired the Senate Committee on Energy and Natural Resources from 2014 to 2015.
Landrieu was defeated in her 2014 re-election campaign by Republican Bill Cassidy, with Cassidy triumphing in a runoff. As of 2026, Landrieu is the most recent Democrat to serve in the U.S. Senate from Louisiana.
Early life and education Landrieu was born in Arlington County, Virginia, on November 23, 1955, and raised in New Orleans, Louisiana. She is the daughter of Moon Landrieu, former mayor of New Orleans and U.S. secretary of the Department of Housing and Urban Development, and the sister of Mitch Landrieu, who was a former mayor of New Orleans and Lieutenant Governor of Louisiana. She was raised as Catholic.
She attended Ursuline Academy in New Orleans. While a student at Ursuline, Landrieu participated in the Close Up Washington civic education program.
In 1977, she graduated from Louisiana State University in Baton Rouge, Louisiana with a Bachelor of Arts degree in sociology, where she was a member of Delta Gamma sorority.
Career After graduating from Louisiana State University, Landrieu worked as a real estate agent.
State legislature Landrieu was first elected to the Louisiana House of Representatives in 1979, serving from 1980 to 1988 and representing a New Orleans district. She was re-elected to the 90th district in October 1983 with 78% of the vote. In October 1987, she was succeeded in the 90th district by her brother Mitch.
On July 25, 1995, The Times-Picayune reported that, as a state representative, Landrieu awarded Tulane University tuition waivers to a former campaign manager.
State treasurer On January 1, 1987, State Treasurer Mary Evelyn Parker, the longtime Democratic incumbent, resigned with nearly a year and a half left in her fifth term. Landrieu ran to succeed her in both the special and regularly scheduled elections, both held in October 1987. No Republican filed to run, so Landrieu faced only Democratic opponents. She came first on both ballots with 44%. She defeated two legislative colleagues, State Rep. Kevin Reilly Sr., chief executive officer of Lamar Advertising Company in Baton Rouge, who came second in the special and regular elections, with 33% and 32%, respectively, and State Rep. Buddy Leach, a former U.S. Representative, who came third in both elections with 15%. Tom Burbank, son of Thomas D. Burbank Sr., former head of the state police, came in last in both elections with 9% of the vote.Louisiana Secretary of State Official Election Results Results, staticresults.sos.la.gov; accessed January 5, 2015. Reilly decided not to contest a runoff election, known in Louisiana as a "general election", and Landrieu won the treasurer's position by default.LA State Treasurer 1987, ourcampaigns.com; accessed January 5, 2015.

1995 gubernatorial election Landrieu declined to run for a third term as Treasurer, giving up the office to run for governor in the 1995 election. The other major candidates in the race were Democratic U.S. Representative Cleo Fields; State Senator Murphy J. Foster, Jr., who switched his party affiliation from Democratic to Republican when he filed; Democratic attorney Phil Preis; Republican former Governor Buddy Roemer; and Democratic Lieutenant Governor Melinda Schwegmann. Landrieu finished third in the state's nonpartisan blanket primary with 18% of the vote, finishing 8,983 votes behind Fields, who came second with 19% of the vote. Roemer came fourth with 18%, Preis was fifth with 9% and Schwegmann came sixth with 5%. Foster came first with 26% and went on to defeat Fields in the runoff with 64% of the vote. Landrieu was succeeded as state treasurer by her fellow Democrat Ken Duncan, a Baton Rouge attorney and businessman.
U.S. Senate Elections
Landrieu was elected in 1996 to the U.S. Senate seat previously held by John Bennett Johnston, Jr. of Shreveport after winning a close and controversial runoff election. (The runoff election is what other states would call "the general election" of a federal seat.) She defeated state Representative Woody Jenkins of Baton Rouge. Landrieu narrowly won re-election in 2002. She defeated state Election Commissioner Suzanne Haik Terrell of New Orleans. Some experts and pundits had considered Landrieu as a possible running mate for presidential candidate John Kerry in the 2004 election before he selected then-Senator John Edwards of North Carolina. In 2004 Landrieu became Louisiana's senior senator upon the retirement of John Breaux, who was succeeded by Republican David Vitter.
In 2008, she won a relatively comfortable 52% to 46% re-election to a third term in a race against her challenger, state Treasurer John Neely Kennedy. He was a former Democrat who switched to the Republican Party in 2007.
Landrieu sought re-election in 2014. Former President Bill Clinton campaigned on her behalf in Louisiana. While Landrieu garnered 42% of the vote she fell short of the 50.1% required for re-election. She was defeated in the December 6, 2014, runoff election by her Republican opponent, Congressman Bill Cassidy, by a 56% to 44% margin.
Tenure In 2002, she voted for the Iraq Resolution, and in 2003 she issued a statement indicating that, "The time for diplomacy has ended." She voted for the Class Action Fairness Act of 2005 and the Protection of Lawful Commerce in Arms Act.
In 2005, Landrieu sponsored a resolution, which the Senate passed in an unprecedented action, to formally apologize for its repeated failure in the early twentieth century to pass anti-lynching legislation.Associated Press, "Senate Apologizes for Not Passing Anti-Lynching Laws" , Fox News; accessed January 5, 2015. The Senate Southern white Democrats had filibustered the Dyer bill in 1922"Filibuster Kills Anti-Lynching Bil", The New York Times, December 3, 1922; accessed July 20, 2011. and two other bills that passed the House. She held high-profile hearings on the mistakes of the Federal Emergency Management Agency (FEMA) in the wake of hurricanes Katrina and Rita in 2005.
Subsequent to the 2006 mid-term elections, in which the Democratic Party gained control of both houses of Congress, Landrieu announced (along with Republican Olympia Snowe of Maine) the formation of the "Common Ground Coalition", a group of moderate senators of both parties, with the goal of finding bipartisan consensus on legislative matters.
Landrieu voted to raise the estate tax exemption to $5 million in 2008, but voted against repeal of the estate tax in 2006.
On December 15, 2008, it was announced that Landrieu would become chairwoman of the Senate Small Business and Entrepreneurship Committee for the 111th Congress when former Chairman John Kerry left to lead the Senate Foreign Relations Committee, previously headed by Vice President-elect Joe Biden.
In September 2010, Landrieu announced she would hold up OMB director Jacob Lew’s confirmation until the administration lifted or eased a federal freeze on deepwater oil-and-gas drilling. Her delay of Lew's nomination came despite broad bipartisan support for appointing him to OMB. The Senate Budget Committee recommended that Lew be confirmed on a 22–1 vote.
According to The Washington Post, Landrieu "is one of the lawmakers leading for more natural gas exports".
On December 18, 2010, Landrieu voted in favor of the Don't Ask, Don't Tell Repeal Act of 2010. In 2011, she became chairman of the Senate's Homeland Security Appropriations Subcommittee, giving her significant influence in the funding of federal agencies like the U.S. Coast Guard, Department of Homeland Security and FEMA. On April 17, 2013, Landrieu voted to expand background checks for gun purchases.
In April 2014, the United States Senate debated the Minimum Wage Fairness Act (S. 1737; 113th Congress). The bill would amend the Fair Labor Standards Act of 1938 (FLSA) to increase the federal minimum wage for employees to $10.10 per hour over the course of a two-year period. The bill was strongly supported by President Barack Obama and many of the Democratic senators, but strongly opposed by Republicans in the Senate and House. She wanted additional debate on the timeline and the raise for tipped workers. Landrieu said that "I do not believe that $10.10 an hour is too high to aspire to, but how quickly we get there and what increments, the tipped wage, how that should be handled, who should get paid the tipped wage, and who shouldn't. There are a lot of questions about that, and some of those discussions are going on."
Health care Landrieu opposed the public health insurance option in the America's Affordable Health Choices Act of 2009 (HR 3200) until the bill was rewritten to send a $300,000,000 payment to Medicaid for her home state. When two pages were added to the bill to place $300 million in Louisiana's Medicaid system, she changed her web page in order to reflect her support of the program. Conservative figures referred to the deal as the "Louisiana Purchase". A typographical error in the bill resulted in $4.3 billion in additional funds for Medicaid for Louisiana. As a result, prominent conservative figures Glenn Beck and Rush Limbaugh called her a "high-priced prostitute". Days later, Sen. Landrieu took to the Senate floor to defend her vote by detailing the timeline of her Medicaid funding request. Landrieu noted her $300 million request was made before President Barack Obama was sworn into office.
On November 21, 2009, Landrieu voted with fifty-nine other senators to bring the health care bill up for debate. On December 8, 2009, she voted against the Nelson–Hatch–Casey amendment which proposed to ban federal funding for private plans that covered elective abortions but would have allowed individuals to purchase separate individual riders that would cover abortions. Prior to a concession of $300 million being added to the bill, Landrieu responded to a question on popular support of the public option, and asserted that the option has popular support because "when people hear 'public option' they hear 'free health care'. Everybody wants free health care. Everybody wants health care they don't have to pay for."
Landrieu voted for the Patient Protection and Affordable Care Act (known as "Obamacare") in December 2009. In September 2013, Landrieu voted to restore funding for the ACA that House Republicans had eliminated in their version of the funding bill.
On March 1, 2012, Landrieu voted against a measure that would have repealed a birth control mandate in the health care bill. In October 2013, she introduced a bill to force health insurance companies to re-issue plans which they have cancelled.
