Ryan Zinke has stepped down as interior secretary, resigning as planned amid a series of ethics investigations. In a tweet he said it's been a "high honor" to serve, adding that the agency has restored public lands, improved public access and "shall never be held hostage again for our energy needs."

So far the president has not nominated anyone as a permanent replacement. The acting secretary is Zinke's deputy David Bernhardt, a lawyer and former lobbyist for the oil industry with longtime experience at the agency.

Lyle St. Goddard, 56, is running along a dirt trail on the Blackfeet Reservation in Montana.

"It takes me about a lap to loosen up," he says.

Being a hotshot is a young man's game and St. Goddard believes he's one of the oldest hotshot crew members in the country.

"I still can do it," he says. "I just got to keep in shape. I'll be okay."

St. Goddard supervises the Chief Mountain Hotshots, one of the big employers of young men and women on the reservation. They only hire Natives and they can promise good pay and the chance to travel all over the country.

Ranking U.S. House Democrats are calling for an ethics investigation into Interior Secretary Ryan Zinke. They want to know more about a land deal between Zinke's family foundation and a real estate project with ties to the oil and gas giant Halliburton.

Family photos cover the walls of a ranch house in eastern Montana. There are pictures of a dad holding a baby and a son playing high school football.

That son, Juan Orozco, sits on a couch next to his mother. He says after his dad came home fromjail a few years ago he just wasn't the same.

"He has bad depression," he says. "He can't sleep, he doesn't want to eat."

On a windy and unseasonably warm winter day in Yellowstone National Park in Montana, spokeswoman Morgan Warthin stands in the middle of a massive, empty valley.

"Yellowstone is so big," she says. "Where do you begin to look?"

She is searching for any of the 52 bison that were set free from two holding pens in mid-January.

Authorities say the bison escaped after somebody used bolt cutters to open up a fence. They soon scattered across an area larger than Delaware, and officials have launched a criminal investigation to find out what happened.
