Landrieu was elected Mayor of New Orleans on February 6, 2010, garnering 66 percent of the citywide vote and claiming victory in 365 of the city's 366 voting precincts. He was reelected mayor on February 1, 2014, with nearly 64 percent of the vote in a three-candidate field[5] and became the first Mayor to win both elections without a runoff and to be elected by majorities of both white and black voters.[6]
On November 14, 2021, President Joe Biden announced that Landrieu would serve as Senior Advisor responsible for coordinating the implementation of the Infrastructure Investment and Jobs Act.[7] He assumed office with the signing of the bill into law on November 15, 2021. He stepped down from his role as the infrastructure implementation coordinator on January 8, 2024, to join Biden's 2024 reelection campaign as a co-chair.[8]
