Karen Carter Peterson

On June 8, 2017, Peterson shouted an obscenity at Representative Dodie Horton of Haughton after Horton asked a group of senators present on the House floor to stop talking so that the budget proceedings being considered could be heard. Peterson later apologized for her verbal attack.

In 2014, Peterson endorsed Senator Mary Landrieu for re-election.

In 2013, Peterson proposed repeal of the Louisiana Science Education Act, a 2008 law which permits science teachers in public schools to use supplemental classroom materials to question evolution as presented in science textbooks. The Senate Education Committee voted 3-2 on May 1 against the repeal. Over seventy Nobel Prize-winning scientists supported Peterson's bill and have urged that the state law be removed. Supporters of the law maintain that it permits critical thinking in the classroom.

In the spring of 2012, Senator Peterson was elected Chair of the Louisiana Democratic Party by the Louisiana Democratic State Central Committee, ousting former chair Claude "Buddy" Leach by a vote of 85 to 75.

In 2010, Peterson won a special election to the Louisiana State Senate from the 5th district after her predecessor, Cheryl Gray Evans, resigned. Peterson served the remainder of Evans' term. In 2011 and 2015, Peterson was re-elected to full four-year terms.

Peterson received endorsements from prominent Republican businessmen Joe Canizaro and Donald T. "Boysie" Bollinger. She was also endorsed by both the Louisiana State Democratic Party and the Orleans Parish branch of the Democratic Party. She centered her campaign around the argument that Jefferson's corruption scandal left New Orleans with a lack of credible and respected representation in Congress. Jefferson, in turn, accused Peterson of profiting from no-bid "sweetheart" contracts with the New Orleans City Council as their legal advisor for utility regulation. In 2009 Jefferson was convicted of eleven felonies.

Although generally a proponent of restrictions on state government spending instead of tax increases to close budgetary shortfalls, Peterson, an avowed non-smoker, supports higher taxes on tobacco and use of the consequent revenue to fund priorities of the Louisiana Healthier Families Act. Her 2009 House Bill 889 (Louisiana Healthier Families Act), after heavy lobbying by both sides, failed in the Louisiana House of Representatives; she attributed the loss to "the national ambition of our governor", Bobby Jindal, whom she claime is interested in the Presidency and wants to seek that office without a tax increase on his record.

Peterson lives in New Orleans' Warehouse District. She is married to Dana Peterson, a political consultant. The couple has no children. She appears in Spike Lee's documentary about Hurricane Katrina, When the Levees Broke. Peterson's sense of humor was manifest during the closing days of the 2009 legislative regular session when a cabinet official in Governor Bobby Jindal's administration accidentally coughed on her after he had tested positive for swine flu virus; the following day, Peterson emerged in the House chamber wearing a hospital mask, prompting colleague state representative Jared Brossett to move that the House be "fully quarantined" until the plague subsided.

Since 2008, Peterson has served as Democratic National Committeewoman for Louisiana. Peterson previously served in the Louisiana House of Representatives.

Peterson was a candidate for U.S. Congress in Louisiana's 2nd congressional district (map) in the mid-term election of November 2006. She, along with several other candidates, challenged incumbent Democrat Bill Jefferson, who was the subject of an FBI investigation. She finished in second place with 19,972 votes (21.6% of the total votes cast), and therefore she and Jefferson entered a runoff round of voting on December 9, 2006. Jefferson prevailed by a 57%-43% margin, the lowest since his original election in 1990.

Peterson served as State Representative for District 93 from 1999 to 2010. Peterson served as House Speaker Pro Tempore from 2008 to 2010.

Peterson is a political protégé of Jim Singleton, a former city councilman and the leader of the powerful Black Organization for Leadership Development (BOLD), which has repeatedly aligned itself in opposition to William J. Jefferson and his Progressive Democrats. With the help of BOLD, Peterson was elected in 1999 to the Louisiana state legislature as a representative for the 93rd district, which encompasses New Orleans, the upper French Quarter, and parts of Central City and Mid-City. In the state legislature, she was one of the most vocal supporters of a plan to reform the New Orleans public school system by putting it under state control. She was also a backer of levee board consolidation after the failures of the New Orleans Levee system following Hurricane Katrina.

Peterson was born and raised in New Orleans, the daughter of Ken and Gwen Carter. Her father was the first Black American to become Tax Assessor in New Orleans. Peterson graduated from Mercy Academy and in 1991 received a bachelor's degree in international business and marketing from Howard University in Washington, D.C. Peterson then returned to New Orleans to receive a law degree from Tulane University in 1995.

Karen Carter Peterson (born November 1, 1969) is a Democratic member of the Louisiana State Senate, having represented the 5th District since 2010. She is also the current Chair of the Louisiana Democratic Party. Peterson is the first woman to serve in this role. In 2017, Karen Carter Peterson was elected for a four-year term as the Vice Chair of Civic Engagement and Voter Participation at the Democratic National Committee, focused on protecting voting rights and expanding voter participation. The position was previously held by Donna Brazile.
