Incoming US President Joe Biden has added more climate staffers to his White House, drawing from the ranks of green groups, environmental advocates and former Democratic administration officials to grow an inner circle that will help him try to slash the nation's greenhouse gas emissions.
The new hires include David Hayes, who served as Interior Department deputy secretary under presidents Bill Clinton and Barack Obama; Cecilia Martinez, a prominent environmental advocate based in Minneapolis who advised the transition team; and Stef Feldman, a top Biden campaign aide who helped craft his climate plan.
