Trump reveals new details of bunker-like ballroom with drone base

U.S. President Donald Trump on Tuesday revealed previously undisclosed details about his new bunker-like White House ballroom, saying it would have a drone base on ​the roof and a military hospital as part of a six-story subterranean complex.

Amid ‌the bang and clang of construction, Trump took a group of reporters on a tour of the project to try to bolster his argument that the U.S. Congress should allocate $1 billion to pay for security enhancements to the building.
