From the article: "When Norton left Interior after five years, she said her primary reason was so she and her husband, John Hughes, could return to "the mountains we love in the West," as well as return to the private sector.
"As Interior secretary, Norton was attacked by environmentalists for her pro-development policies regarding oil and gas, coal and timber. She also reopened Yellowstone National Park to snowmobiles.
"Industry advocates and Norton's fellow Republicans, however, have praised her as a realist willing to open public lands to drilling during a time of energy shortages that threatened the economy."
