Photos tweeted by political journalists in the US showed that the President had re-adorned the walls of the West Wing in the White House with photos of his summit with the North Korean leader.
The new photos took the place of images taken during the French President’s visit to Washington DC last month.
The tweets showed six photos on the wall at the top of the West Wing Staircase.
Images include the moment Kim and Mr Trump signed an agreement committing to denuclearisation.
Another photo shows US citizens returning home after being released from prison in North Korea.

The wall also includes an image taken during a visit from the top North Korean aide Kim Yong Chol to the White House, where he delivered a letter from Kim Jong-un pledging to go ahead with the summit in Singapore.
Mr Trump described his meeting with Kim as a “tremendous success.”
The US president announced that US-led military exercise, or “war games”, to counter the North Korean threat would be called off as diplomacy is ramped up, though economic sanctions would remain for the time being.
The President’s improved relationship with the North Korean leader came as he received criticism from US allies over his decision to impose international tariffs on goods including steel and aluminium imports.
The move drew criticism from Mr Macron, German Chancellor Angela Merkel and Canada’s Prime Minister Justin Trudeau, among others.
Tensions with US allies were further ramped up when Mr Trump said he would not sign onto a joint communique issued by the G7.
