President Trump previously said his ballroom addition to the White House East Wing wouldn't "interfere" with the building's existing structure.

The Trump administration has been defending the demolition work which has begun on part of the White House, to allow the construction of a new $250m (£149m) ballroom.

“I am pleased to announce that ground has been broken on the White House grounds to build the new, big, beautiful White House ballroom,” Mr Trump posted on his Truth Social social media platform.
