Presidential Emergency Operations Center

The Presidential Emergency Operations Center (PEOC, ) is a bunker-like structure underneath the East Wing of the White House. It serves as a secure shelter and communications center for the President of the United States and others in case of an emergency.
History.
The first White House bunker was constructed during World War II to protect President Franklin D. Roosevelt in the event of an aerial attack on Washington. The modern PEOC space has modern communications equipment including televisions and phones to coordinate with outside government entities. During a breach of White House security, including violations of the Washington, D.C. Air Defense Identification Zone (P-56 airspace), the President and other protectees are relocated to the executive briefing room, next to the PEOC. Day to day, the PEOC is manned around the clock by joint-service military officers and non-commissioned officers.

During the September 11 attacks, a number of key personnel were evacuated from their offices in the White House to the PEOC.

President George W. Bush was in Florida at the time of the attacks.

President Donald Trump relocated to the PEOC during the night of May 29, 2020, at the beginning of protests following the killing by police of George Floyd. After this was reported by the news media, Trump demanded that officials find and prosecute those responsible for the information getting to them.
