The Marine was standing at attention next to Mr Trump's helicopter, Marine One, when a gust of wind knocked his hat off his head. As per protocol, the Marine remained still and didn't move to pick up his hat. (The US Marine Corps refers to the hat as a cover.)
Mr Trump, who was talking to a military official, immediately bent down to pick up the hat. He then walked over and placed it firmly on the young Marine's head and gave him a pat on the arm.

Immediately, however, the white hat flew off the Marine's head once again. This time, both Mr Trump's military escort and the president himself chased after it. They both reached down to pick it up. Mr Trump appeared to hand the hat over to the officer, leaving it up to him to return the Marine's hat. Mr Trump then boarded the chopper.
