“Now the military is building a big complex under the ballroom, which has come out recently because of a stupid lawsuit that was filed. But ​the military is building a massive complex under the ballroom, and that’s ​under construction,” Trump said.

“The ballroom essentially becomes a shed for what’s being built under … including from ‌drones ⁠and including from any other thing.”

The 90,000-square-foot (8,360-square-meter) ballroom will replace the East Wing, which Trump ordered demolished in October. Underneath that building was the Presidential Emergency Operations Center, an emergency bunker for the president.
