First lady Melania Trump does not accompany her husband to Vietnam, as Beijing was the third and final leg of her trip to Asia with the president, the U.S. head of government said on Twitter.

"Melania is staying behind to see the zoo, and of course, the Great WALL of China before going to Alaska to greet our AMAZING troops," Trump said.
