A man has been charged with trying to assassinate Donald Trump after allegedly staking out the former president on his Florida golf course for around 12 hours.
Ryan Routh was arrested after a rifle was seen poking through bushes at the West Palm Beach course on 15 September.
A Secret Service agent, who was a hole ahead of Trump, opened fire and the suspect fled but was detained less than an hour later.
Routh, 58, was initially charged with two gun offences but prosecutors have now added to the indictment.
They said Routh left a note, written months before his arrest, signalling his intention to kill Trump.
It was dropped off at the home of an unidentified person who contacted authorities following his arrest, said the US Justice Department.
Prosecutors said it states: “This was an assassination attempt on Donald Trump but I failed you. I tried my best and gave it all the gumption I could muster.”
The note was headlined “Dear World” and allegedly offered $150,000 (£111,000) for anyone who could “finish the job”.
A handwritten list of dates and locations where Trump was expected to be was also found on him, according to prosecutors.
Routh is said to have spent a month in southern Florida with mobile phone data showing him near the golf course and Trump’s home.
Authorities said six phones, including one showing a Google search of how to travel from Palm Beach to Mexico, were also found in his car.
The golf course incident came two months after Trump survived an attempt on his life while on stage in Pennsylvania.
Routh also faces charges of assaulting a federal officer, possessing a firearm in furtherance of a crime of violence, and the two original firearms charges from last week.
He has not yet entered a plea.
