President Biden named former New Orleans Mayor Mitch Landrieu as senior adviser and infrastructure coordinator on the $1 trillion infrastructure bill, the White House confirmed Sunday.

Landrieu, who led New Orleans from 2010 to 2018, was also a lieutenant governor for Louisiana. The White House said they chose him because of his experience leading the city, as well as for his relationships with leaders at both state and municipal levels.

"In this role, Landrieu will oversee the most significant and comprehensive investments in American infrastructure in generations—work that independent experts verify will create millions of high-paying, union jobs while boosting our economic competitiveness in the world, strengthening our supply chains, and acting against inflation for the long term," the White House said.
