On June 18, 2016, Michael Steven Sandford was arrested at a Donald Trump presidential campaign rally in Las Vegas, Nevada in the United States after he failed to seize the pistol of a Las Vegas Metropolitan Police officer providing security for the event. At the time, Trump was the presumptive nominee of the Republican Party for the 2016 United States presidential election.
Sandford, a 20-year-old British citizen who had a lengthy history of mental disorders, stated that he had wished to kill Trump to prevent him from becoming President. He was charged with impeding and disrupting the orderly conduct of government business and official functions and with being an illegal alien in possession of a firearm. On September 13, 2016, he pled guilty to both charges. On December 13, 2016, he was sentenced to 12 months and one day imprisonment. He was released and deported to the United Kingdom in May 2017.
The incident received limited media coverage in the United States. Some conservative publications criticized the length of Sandford's prison sentence. In the United Kingdom, the incident prompted calls for changes to the Mental Capacity Act in light of Sandford's mental disorders and was the subject of a BBC documentary.
