Interior Secretary Ken Salazar is ending months of speculation about his future and will step down by the end of March.
The Denver Post first reported the news early Wednesday, and Salazar made the news official just before 10 a.m.
“Colorado is and will always be my home,” said Salazar, who previously represented the state in the Senate. He added: “I have had the privilege of reforming the Department of the Interior to help lead the United States in securing a new energy frontier, ushering in a conservation agenda for the 21st century, and honoring our word to the nation’s first Americans."
The White House quickly issued a statement from President Barack Obama praising Salazar and saying he had "played an integral role in my administration’s successful efforts to expand responsible development of our nation’s domestic energy resources."
