Crooks was seen carrying a backpack about 5.56pm, less than 20 minutes before the shooting took place, and at 6.08pm he was caught on a police dashboard camera walking on the roof from where he ultimately fired the shots, Mr Rojek said.
Although the FBI is not the agency responsible for investigating any lapses in Trump’s security, FBI personnel are putting together a timeline of events, he said.
FBI officials said they had yet to identify a motive for Crooks, who was shot dead by a Secret Service agent after opening fire.
Trump will ‘probably’ debate Harris
Fox News host Laura Ingraham repeatedly pressed Trump during the interview on whether he would commit to a debate with Kamala Harris.
“I want to do a debate. But I also can say this. Everybody knows who I am. And now people know who she is,” Trump said.
Trump eventually said: “The answer is yes, I’ll probably end up debating.”
He went on for a minute, saying any debates need to be held before early voting starts in states, and then added: “I can also make a case for not doing it.”
The Republican presidential nominee also backed his running mate, Senator JD Vance, over past comments about “childless cat ladies” that have gone viral and become a political headache for their White House campaign.
