The attempts on Trump’s life in 2017.

[Robert DeLong]

September 6, 2017: Gregory Lee Leingang, a 42-year-old man from North Dakota, attempted to assassinate President Donald Trump in Mandan, North Dakota, while Trump was visiting the state to rally public support. Leingang stole a forklift from an oil refinery and drove toward the presidential motorcade. After the forklift became jammed within the refinery, he fled on foot and was arrested by the pursuing police. While interviewed in detention, he admitted his intent to murder the president by flipping the presidential limousine with the stolen forklift, to the surprise of authorities, who suspected he was merely stealing the vehicle for personal use. The man pleaded guilty to the attempted attack, stealing the forklift, related charges and several other unrelated crimes on the same day. Consequently, he was sentenced to 20 years in prison. His defense attorney noted a "serious psychiatric crisis". Leingang's choice of a forklift as a weapon was unique among presidential assassination attempts.

November 2017: A man affiliated with the Islamic State of Iraq and the Levant (ISIL), whose name was not revealed, was arrested by the Philippine National Police in Rizal Park, Manila, for reportedly planning to assassinate Trump during the diplomatic ASEAN Summit. In the week prior to the failed killing, the Secret Service already suspected a planned assault on the president because of the general presence of ISIL in the Philippines and because of threats by many people against the president on social media. Before the landing of Trump's airplane, the Secret Service discovered a credible terrorist threat from a man who threatened to kill the president on social media, quickly tracking down and arresting the terrorist. The government disclosed the incident to the public after a year of silence in a television documentary.
