Zinke and Interior Twitter accounts posted photos that showed him in a black cowboy hat astride a brown bay roan gelding that stands just over 17 hands tall, a bus and typical morning traffic in the background.

The National Rifle Association applauds Secretary Zinke's decision to withdraw Director's Order No. 219, a decree imposed on the final day of the Obama presidency to ban the use of lead ammunition and fishing tackle on national wildlife refuges. "Between hunting, fishing, motorized recreation, camping and more, the industry generates thousands of jobs and billions of dollars in economic activity", said Zinke.

The Center for Biological Diversity, for examples, said up to 20 million birds and other animals die of lead poisoning each year from the 100,000 tons of lead left on lands by hunters and fishers, as well as other sports enthusiasts.

In his first day on the job, Secretary Zinke issued two secretarial orders focused on hunters and anglers.

Those orders include limits to drilling in sensitive offshore areas like the Atlantic coast and Arctic, as well as a ban on new federal coal mining leases.

NRECA noted that numerous regulatory issues that impact electric cooperatives fall under the Interior Department's jurisdiction, including land-use activities, rights-of-way, and the Endangered Species Act rules administered by Interior's Fish and Wildlife Service. The first overturns the Use of Nontoxic Ammunition and Fishing Tackle order, which had banned lead bullets and fish tackle on Fish and Wildlife Service lands.

To that end, I have three main priorities that I hope you will join with me in working to achieve.

Zinke also pledged to tackle an estimated $12 billion backlog in maintenance and fix at national parks and stand firm against attempts to sell, give away or transfer federal lands.

"We serve the people, not the other way around", he wrote. Ranchers who hold grazing permits on public land do vital work that benefits public land including the improvement of water sources, improvement of wildlife habitat, and maintaining the open space that Americans enjoy, yet are often targeted by outside interest groups. "I think where there's debate on it is what that influence is [and] what can we do about it". I will do everything in my power to ensure respect to the sovereign Indian Nations and territories.
