45th President Donald J. Trump’s former Interior Secretary Ryan Zinke just narrowly won his GOP primary for a seat in the U.S. House of Representatives from the state of Montana, where he previously served.

The Daily Caller reports:

Former U.S. Interior Secretary Ryan Zinke, who served in the Trump administration between 2017 and 2019, narrowly won the nomination with 41.7% of the vote, Reuters reported. Former state lawmaker Dr. Albert Olszewski, one of four Republicans vying for the spot, received 39.8% of the vote.

The primary was held Tuesday, but a winner was not projected until Thursday.

Trump endorsed Zinke in May, adding another win to the former president’s record in contested primaries, Reuters reported. His success rate thus far has been mixed, consisting of both wins, such as the Ohio and Pennsylvania Senate primaries, and losses, such as Georgia‘s gubernatorial primary.

Zinke served in the House before taking the interior secretary post, Reuters reported. He resigned after his use of security details, chartered flights and a real estate deal drew scrutiny, but has consistently denied abusing the position.
