But of all the construction projects Trump is pursuing, the renovations at Dulles could prove to be his most popular and benefit the greatest number of people. The airport, the area's primary international airport, served roughly 29 million passengers over the past year, according to the Metropolitan Washington Airports Authority. "We're doing something with Dulles that's going to make it the top anywhere in the world." Trump, who used a laser pointer to explain the renovations displayed on renderings, said the "crazy distances" travelers must walk to get from place to place make Dulles "the worst airport." Trump and Duffy said the president reviewed presentations from about 30 architects before Trump settled on the redesign he announced Wednesday.
