The gunman who tried to assassinate Donald Trump spent months researching him, along with other targets like Joe Biden, before deciding to shoot the Republican presidential candidate, the FBI has said.
The bureau said Thomas Crooks, 20, was involved in a “sustained detailed effort to plan an attack” before eventually becoming “hyper focused” on Mr Trump’s rally in Pennsylvania.
But Kevin Rojek, the special agent in charge of the FBI’s Pittsburgh field office, has also admitted experts have not yet been able to determine what motivated him.
Crooks’ computer activity showed he was interested in a mix of ideologies, but did not show a definitive motivation from a particular left-leaning or right-leaning point of view.
Mr Trump was struck in the ear when Crooks, who was positioned on the roof of a nearby building, fired eight shots before being killed by a Secret Service counter sniper.

Video evidence shows he was only on the roof for about six minutes, killing one person and wounding two others when he opened fire at the event on 13 July.
Crooks, who left several explosive devices in his car, had searched for information about bomb components as early as 2019.

Trump gunman’s motive ‘unclear’

Crooks searched for Mr Trump’s campaign events as early as September 2023 and continued looking for rallies for both candidates near where he lived in western Pennsylvania, and the dates of both the Republican and Democratic presidential conventions.
Mr Rojek described how Crooks eventually became “hyper focused” on the Trump rally in Butler, Pennsylvania, when it was announced in early July “and looked at it as a target of opportunity”.
In the days leading up to the event, he researched information about the site, including where Trump would speak.
His online search history revealed questions and phrases like: “Where will Trump speak from at Butler Farm Show?”, “Butler Farm Show podium” and “Butler Farm Show photos”.

The FBI says it has already conducted nearly 1,000 interviews.
The new details suggest Crooks was a man who investigators believe had a strong interest in explosives, major events and prominent political figures, but they have not been able to assign a single motive.
“We have a clear idea of mindset, but we are not ready to make any conclusive statements regarding motive at this time,” Mr Rojek said.
Officials say they have not found any evidence Crooks worked with other people, or had been directed by a foreign power.
There were also no traces of illegal drugs or alcohol in his system.
Meanwhile in an interview with talk show host “Dr Phil” McGraw, Donald Trump claimed that Joe Biden and Kamala Harris made it difficult for him to have adequate Secret Service protection at his campaign rallies.
The former president said: “He (Joe Biden) always made it very tough for us to have the proper number of Secret Service people.”
He added: “I don’t know whose fault it is, but I will tell you, I’d have these massive rallies with 50-60,000 people, more, and our people were always fighting to get more security, more Secret Service, and he knew that we didn’t have enough”.
Preliminary investigations determined there were significant failures by the Secret Service.
Donald Trump has filed a defamation lawsuit against the BBC, alleging the corporation’s Panorama documentary portrayed him in a “false, defamatory, deceptive, disparaging, inflammatory, and malicious” manner.
The complaint relates to the broadcaster’s editing of a speech he made in 2021 on the day his supporters overran the Capitol building.
Clips were spliced together from sections of the US president‘s speech on January 6 2021 to make it appear he told supporters he was going to walk to the US Capitol with them to “fight like hell”.
It aired in the documentary Trump: A Second Chance?, which was broadcast by the BBC the week before last year’s US election.
The US president is seeking damages of no less than $5bn (£3.7bn).
He has also sued for $5bn for alleged violation of a trade practices law. Both lawsuits have been filed in Florida.

BBC crisis: How did it happen?
‘They put words in my mouth’
Speaking in the Oval Office earlier on Monday, he said: “In a little while, you’ll be seeing I’m suing the BBC for putting words in my mouth.
“Literally, they put words in my mouth. They had me saying things that I never said coming out.”
The scandal erupted earlier this year after a leaked memo highlighted concerns over the way the clips were edited.
After the leak, BBC chair Samir Shah apologised on behalf of the broadcaster over an “error of judgement” and accepted the editing of the 2024 documentary gave “the impression of a direct call for violent action”.
The fallout from the saga led to the resignation of both the BBC director-general Tim Davie and the head of news Deborah Turness.
Earlier, BBC News reported the broadcaster had set out five main arguments in a letter to Mr Trump’s legal team as to why it did not believe there was a basis for a defamation claim.
In November, the BBC officially apologised to the president, adding that it was an “error of judgement” and saying the programme will “not be broadcast again in this form on any BBC platforms”.
A spokesperson said “the BBC sincerely regrets the manner in which the video clip was edited,” but they also added that “we strongly disagree there is a basis for a defamation claim”.
Four people have been charged with plotting New Year’s Eve bomb attacks in California.
Federal authorities in the US said the four are allegedly part of an extremist group which is suspected of planning the attacks in southern California.
The plot consisted of planting explosive devices at five locations targeting two US companies at midnight on New Year’s Eve in the Los Angeles area.
The suspects were arrested last week in Lucerne Valley, a desert city east of Los Angeles.

They are said to be members of an offshoot of a pro-Palestinian, anti-government and anti-capitalist group dubbed the Turtle Island Liberation Front, the complaint said.
As well as the alleged plan against the two companies, the group also planned to target Immigration and Customs Enforcement (ICE) agents and vehicles, attorney general Pam Bondi said.
The four defendants named in the complaint are Audrey Illeene Carroll, Zachary Aaron Page, Dante Gaffield, and Tina Lai.
All four are from the Los Angeles area, according to first assistant US attorney Bill Essayli.
The alleged plot
According to a sworn statement by the complaint, Carroll showed an eight-page handwritten document to a paid confidential source in November, which described a bomb plot.
The document was titled “Operation Midnight”.
Essayli said one of the suspects created a detailed plan that “included step-by-step instructions to build IEDs (improvised explosive device)… and listed multiple targets across Orange County and Los Angeles.”

Carroll and Page are then alleged to have recruited the other two defendants to help them carry out the plan which included acquiring bomb-making materials before constructing and performing test detonations.
Under the plan, the defendants would supposedly have travelled to a remote location in the Mojave Desert on the 12 December to construct and detonate their test explosive devices, the sworn statement alleges.
Evidence photos included in the court documents show a desert campsite with what investigators said were bomb-making materials strewn across plastic folding tables.
The FBI said agents intervened before the defendants could complete their work to assemble a functional explosive device.
