President-elect Trump on Tuesday announced he was choosing Pete Hegseth, an Army veteran and a Fox News host, to serve as Defense secretary.

Hegseth served as an infantry captain in the Army National Guard and did tours in Afghanistan and Iraq, earning two Bronze Stars. He is currently a co-host for “Fox & Friends Weekend.”

“Pete is tough, smart and a true believer in America First. With Pete at the helm, America’s enemies are on notice – Our Military will be Great Again, and America will Never Back Down,” Trump said in a statement.

The president-elect also used his statement to promote Hegseth’s new book, as well as his work with veterans advocacy groups.

“Nobody fights harder for the Troops, and Pete will be a courageous and patriotic champion of our ‘Peace through Strength’ policy,” Trump added.
