President Donald Trump's waded into the contentious debate over paper versus plastic straws with an executive order Monday favoring the plastic variety. The president ordered federal agency and department heads to stop buying paper straws and make sure they aren't offered in their buildings.

President Donald Trump on Monday signed an executive order aimed at encouraging the U.S. government and consumers to purchase plastic drinking straws. "We're going back to plastic straws," Trump told reporters at the White House as he signed the order.

An executive order from President Trump will negate a Biden initiative that required federal procurement offices to purchase paper straws in lieu of plastic.
