New details have emerged about a "top secret" construction project taking place underneath the White House. A new CNN report includes what little is known about the construction efforts, focused on a defensive bunker underneath what was formerly the East Wing of the White House. The East Wing, which was controversially demolished by President Donald Trump in October in order to build his own $400 million ballroom, sat atop a secure underground facility built by President Franklin D. Roosevelt during World War II. The facility beneath the former East Wing previously housed the Presidential Emergency Operations Center, which was utilized during the Sept. 11 attacks and later by Trump in May 2020 during the George Floyd protests.
