President Trump has signed a directive aimed at toughening enforcement of federal Buy American policies for government purchases and for products used on federally funded projects. The executive order, which Trump signed on April 18, also has  provisions that seek to counter what administration officials call abuses in the H-1B visa system for skilled workers.

The directive follows up on Trump’s repeated comments that he will put a priority on “Buy American” and “Hire American” policies, including a mention in his Feb. 28 address to Congress.
