WASHINGTON (Reuters) - President Donald Trump signed an executive order formally withdrawing the United States from the 12-nation Trans-Pacific Partnership trade deal on Monday, following through on a promise from his campaign last year. In an Oval Office ceremony, Trump also signed an order imposing a federal hiring freeze and a directive banning U.S. non-governmental organizations receive federal funding from providing abortions abroad. Trump called the TPP order a “great thing for the American worker.”
