An administration official says Interior Secretary Ken Salazar will leave the Obama administration in March.
Salazar has run the Interior Department throughout President Barack Obama's first term. Before joining the Cabinet, he served as a senator from Colorado.
Salazar is the latest Cabinet secretary to leave the administration as Obama heads into his second term. Secretary of State Hillary Rodham Clinton, Pentagon chief Leon Panetta, Treasury Secretary Timothy Geithner and Labor Secretary Hilda Solis are also leaving.
Salazar, a fifth-generation Coloradoan, has served his state and the nation for 14 continuous years as Colorado Attorney General, United States Senator and as the 50th secretary of the U.S. Department of the Interior.
Nevada Senator Harry Reid issued the following statement after Secretary of the Interior Ken Salazar:
"In my thirty years of service in Congress, I have never worked with a better steward of our nation's precious natural resources than Ken Salazar. Growing up in his family's ranch in Colorado, Ken always understood and respected the importance of protecting our country's natural wealth. He approached his job as a man of the land because that is exactly what he is, with deep roots to the Mountain West.
"I could not have asked for a better partner than Ken for continuing to build a clean-energy economy in Nevada. He knows full well that our economic future depends on energy independence and middle class jobs that cannot be exported. His commitment and dedication in this very important job set a high bar. I wish him the best in the next chapter of his life and thank him for his friendship and his unwavering commitment to serving our nation."
