Trump pulls back curtain on White House ballroom's fortress-like defenses above and deep below

President Donald Trump gave reporters a fresh look Tuesday at construction of the new White House ballroom, touting it as a hardened security structure that runs six stories into the ground.

"This goes down very deep," Trump said Tuesday from outside of the White House, motioning for reporters to check out construction updates. "You get a better view right over here. … These are already down two floors. That is down about six stories deep. That's big stuff. Normally, when you build a ballroom, you build it flat. You just throw the ballroom. It would have been built."
