List of White House security breaches

Extensive measures are used to protect the White House as the official residence (Executive Residence), office space (West Wing) of the President of the United States, and grounds. Security is primarily provided by the United States Secret Service. Since the September 11 attacks, the restricted airspace above the White House has been expanded and better enforced. Despite security measures such as a fence, however, there have been some people who have managed to gain access to the White House without permission from the President.

Fence

Currently, a fence surrounds the White House, but it did not always exist. Though at various points since the time of Thomas Jefferson, various fences and gates were added to shape or constrain public access, greater public access to the White House grounds than was common in comparable European institutions was possible (with some restrictions) up until World War II. After World War II, public access to the White House grounds has been increasingly restricted.^[1] During the mid-1990s, the fence was expanded by one block to move traffic farther from the White House to prevent damage from any car bomb.^[2]
