US Interior Secretary To Leave Administration

US Interior Secretary Ryan Zinke is leaving his post at the end of the year, President Donald Trump says, in the latest high profile departure from his administration.

In a tweet, President Trump Thanked Mr Zinke for his service, saying he had "achieved much during his tenure".

He said he would appoint a new interior secretary next week.

Mr Zinke, an ex-navy seal and a former Montana Congressman, has been embroiled in allegations of ethics violations.

The interior department oversees federal land, including national parks such as Yosemite and Yellowstone.

Mr Zinke has faced scrutiny over expensive trips in us park police helicopters and on private jets.

Costly alterations at his department also came in for criticism, including reports that three sets of double doors in his office were being upgraded at a cost of nearly one hundred thirty-nine us dollars. He later said he had negotiated the price down to seventy-five thousands dollars.

The New York Times has also published a guide to the investigations into Mr Zinke.

According to the newspaper, he is facing scrutiny for blocking a Native American casino expansion after meetings with lobbyists opposing the plan, and for possible breaches of the hatch act which stops federal employees from influencing elections by using their office.
