Trump: White House ballroom to be 'drone-proof' with military complex

US President Donald Trump spoke to reporters at the construction site of his planned White House ballroom, saying the estimated $400 million project is set to be "drone-proof" and include a military-style complex beneath the facility.

Trump said the ballroom is being funded by private donors and is ahead of schedule. The project, however, has faced new hurdles after the Senate parliamentarian ruled against a $1 billion provision in a bill intended to help fund it.
