President Trump abandons his open umbrella at the door to Air Force One while departing for Indianapolis on Saturday. Donald Trump may need a bit more work to master umbrellas use and etiquette, as a viral video showed. Trump was seen boarding Air Force One on Saturday holding an oversized umbrella to keep out of the driving Washington, D.C., rain. But as he reached the top of the stairs leading to the plane, Trump gave a half-hearted attempt to close the umbrella before finally giving up and simply leaving it blowing at the top of the platform. The black umbrella flopped around for a few minutes, and a longer version of the video shows someone else follow up the stairs to board Air Force One. Instead of picking up the umbrella or closing it for the president, the person simply walks around it and boards the plane.
