Trump says his administration 'will follow two simple rules' once he's sworn in as president

On the campaign trail, President-elect Donald Trump ran against Democratic rival Hillary Clinton as a populist, nationalist candidate, so it's no surprise he's doubling down on a pledge to live by "two simple rules" regarding the U.S. economy.

In an Instagram post Thursday morning, the president-elect promised to "buy American and hire American" while he's in the White House.

My Administration will follow two simple rules: BUY AMERICAN and HIRE AMERICAN! #USA

Throughout the campaign, Trump repeatedly claimed he would be able to bring jobs back to the United States, despite the fact that the Trump Organization has hired foreign workers over the years.

"Remember years ago, we used to proudly display 'Made in the USA.' ... We don't see it," Trump said during a victory rally in Des Moines, Iowa, earlier this month. "I don't see it anymore. We ought to start doing that. Any of the manufacturers that were doing a lot of talking to a lot of companies that were thinking about leaving, and I tell ya, I don't think they're going to be leaving so fast anymore."

Trump shared the post after he touted two announcements Wednesday from companies that have vowed to hire American workers. The billionaire businessman has credited and thanked himself for the positive news in the job market.

To his detractors, Trump's promise to "hire American" is somewhat ironic. According to a report earlier this month, the Trump Winery in Virginia is seeking permission to hire foreign workers and the president-elect will hire foreigners to work in his Florida estate, Mar-a-Lago, this winter.
