President Trump wasn't just cheering on his way to a 9/11 memorial service in Shanksville, Pennsylvania. He was also apparently scoping out ideas for his border wall. While thanking America's "brave patriots" at a somber service earlier this month, Trump also noticed the "gorgeous wall where the plane went down," he said in an interview with The Hill on Tuesday. The "beautiful" wall, as Trump described it, is a memorial in honor of the 40 passengers and crew members who fought hijackers to down their plane before it hit Washington on 9/11.
