President Trump is known for his weird habits, such as his now legendary sideways handshake.
Love him or loathe him, he's never afraid to do things a little - or a lot - differently.
In very serious breaking news, it's emerged that the president, the leader of the free world, doesn't seem to know how to use an umbrella.
This earth shattering revelation was revealed as Trump boarded the presidential plane, Air Force One. Before entering the aircraft, he paused, before leaving his open umbrella at the door.
The umbrella was left, eerily hovering open outside the air craft for all to see.
Naturally, given this bizarre video, the Internet had a field day.
This isn't the first time Trump's umbrella usage has raised eyebrows. He was previously criticised for not sharing his umbrella with his wife Melania.
