The 2014 White House intrusion occurred on September 19, 2014, when Omar J. Gonzalez, an Iraq War veteran with post-traumatic stress disorder, jumped over the White House's fence and entered the building's front door, overpowered a female security officer, was stopped by another who was off-duty, then later by multiple security officers, and arrested. He was found to have a small knife in his pocket, and stated that the "atmosphere was collapsing" and he needed to tell the president so that he could alert the public. President Barack Obama and his family were not home at the time of the incident. As a result of this incident and other security breaches at the White House, the then-director of the United States Secret Service, Julia Pierson, resigned from her position on October 1, 2014.
