List of White House security breaches
From Wikipedia, the free encyclopedia
Extensive measures are used to protect the White House as the official residence (Executive Residence) and office space (West Wing) of the president of the United States, and grounds. Security is primarily provided by the United States Secret Service. Despite security measures (such as a fence), there have been some people who have still managed to gain unauthorized access to the White House.
Many of the intruders were "pranksters or harmless people with mental illnesses"; however, some have entered with the intention of harming people.[1]
