WASHINGTON (AP) — Louisiana Democratic Rep. Troy Carter is the newest member of the House of Representatives. His swearing-in Tuesday adds some breathing room to the party’s tight majority. The 57-year-old Carter represents a majority-Black district centered in New Orleans that extends up the Mississippi River into Baton Rouge. The seat opened after Democratic Rep. Cedric Richmond left the position to work as a special adviser to President Joe Biden. Carter’s swearing-in gives Democrats a 219-212 edge in the House, with four vacancies. Carter says he’ll work with lawmakers from both parties and the White House to meet his district’s needs.
