President-elect Donald Trump said Tuesday that he is nominating Fox News host and decorated Army veteran Pete Hegseth to serve as his defense secretary.

The 44-year-old deployed to Iraq and Afghanistan and won two Bronze Stars, then unsuccessfully ran for Senate in Minnesota in 2012 before joining Fox News.

‘Pete is tough, smart and a true believer in America First,’ Trump said in a statement, as he spent much of Tuesday adding to his cabinet.

The appointment comes just hours after former Democrat Congresswoman and Trump ally Tulsi Gabbard said she’d wanted the job.

‘With Pete at the helm, America´s enemies are on notice – Our Military will be Great Again, and America will Never Back Down,’ Trump added.

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

‘Pete Hegseth has been an exceptional host on FOX & Friends and FOX Nation and a best-selling author for FOX News Books for nearly a decade,’ a spokesperson for Fox News Media told DailyMail.com in a statement.

‘His insights and analysis especially about the military resonated deeply with our viewers and made the program the major success that it is today. We are extremely proud of his work at FOX News Media and wish him the best of luck in Washington.’

Trump is rolling out a steady stream of appointees and nominees for his upcoming administration, working thus far at a faster pace and without as much drama as his first transition following his 2016 victory.

Hegseth, 44, is a co-host of Fox News Channel´s ‘Fox & Friends Weekend’ and has been a contributor with the network since 2014, where he developed a friendship with Trump, who made regular appearances on the show.

He is also the author of ‘The War on Warriors: Behind the Betrayal of the Men Who Keep Us Free.’

The book, according to its promo, combines ‘his own war experiences, tales of outrage, and an incisive look at how the chain of command got so kinked,’ and bills itself as ‘the key to saving our warriors – and winning future wars.’

While the Pentagon is considered a key coveted post in any administration, the defense secretary was a tumultuous post during Trump´s first term.

Five men held the job during his four years only to resign, be fired or serve briefly as a stopgap. Just two of them were actually confirmed by the Senate.

Trump´s relationship with his civilian and military leaders during those years was fraught with tension, confusion and frustration, as they struggled to temper or even simply interpret presidential tweets and pronouncements that blindsided them with abrupt policy decisions they weren´t prepared to explain or defend.

Many of the generals who worked in his first administration – both on active duty and retired – have slammed him as unfit to serve in the Oval Office and he has condemned them in return.

Hegseth was an infantry captain in the Army National Guard and served overseas in Afghanistan, Iraq and Guantanamo Bay, Cuba.

He was formerly head of the Concerned Veterans for America, a group backed by conservative billionaires Charles and David Koch.

If confirmed by the Senate, he would inherit the top job during a series of global crises – ranging from Russia´s war in Ukraine and the ongoing attacks in the Middle East by Iranian proxies to the push for a cease-fire between Israel, Hamas and Hezbollah and escalating worries about the growing alliance between Russia and North Korea.

On a recent appearance on Fox News, he made it clear that he felt Joe Biden’s White House – run by Secretary of Defense Lloyd Austin – was run by ‘pro-Palestinian millennials.’

‘What Israel is about to do is bring Hell down on Hamas. Israel is about to do real war. Israel will be stacking bodies because Netanyahu isn’t messing around,’ he said.

Hegseth has ‘an excellent background as a junior officer but does not have the senior national security experience that secretaries need,’ said Mark Cancian, a senior advisor at the Center for Strategic and International Studies.

‘I think Trump was tired of fighting with his secretaries of defense and picked one who would be loyal to him.’ Cancian said the lack of experience might make it more difficult for Hegseth to get through Senate confirmation.

Gabbard, a Democrat Congresswoman from Hawaii who became a Republican after endorsing Trump, had her eyes set on the gig, according the New York Post.

In a story published earlier today, it was believe Gabbard’s biggest opponent for the job was former Veterans Affairs Secretary Robert Wilkie, suggesting Trump may have played a Wild Card.

The Hegseth announcement was part of Trump’s moves to build out his national security team Tuesday

In a flurry of announcements, Trump said he had chosen former Arkansas Gov. Mike Huckabee as ambassador to Israel and his longtime friend Steven Witkoff to be a special envoy to the Middle East.

Trump also said he would nominate South Dakota Gov. Kristi Noem to run the Department of Homeland Security and named Bill McGinley, his Cabinet secretary in his first administration, as his White House counsel.
