Louisiana state Sen. Troy Carter (D) defeated his colleague, state Sen. Karen Carter Peterson (D), in a special election Saturday for Louisiana's 2nd Congressional District seat, a majority-Black district that includes most of New Orleans and extends into Baton Rouge, according to AP.

Why it matters: Carter, who is known for being willing to work across party lines, secured several high-profile endorsements before the race, including the No. 3 Democrat in the House of Representatives, Rep. Jim Clyburn (S.C.).

Context: The seat was left vacant after President Biden tapped Cedric Richmond to serve as the White House director of public engagement.

• Richmond and several other Congress members endorsed Carter in April.
• Stacy Abrams, the former Georgia House minority leader and 2018 Democratic gubernatorial candidate in Georgia, and LaToya Cantrell, mayor of New Orleans, both endorsed Peterson.
