New Details:
The timeline was briefed as follows:
- 5:10 Crooks was first identified as a person of interest
- 5:30 Crooks was spotted with a rangefinder
- 5:52 Crooks was spotted on the roof by Secret Service
- 6:02 Trump takes the stage
- 6:12 Crooks fires first shots
From the time he fired his first shot to Crooks being killed was just 26 seconds, according to law enforcement officials. Eleven seconds after the first shot, USSS counter snipers acquired their target -- and 15 seconds after that, Crooks was shot dead.
Briefers told lawmakers Crooks purchased the ammo box at Walmart on July 5, two days after the rally was announced. On July 13, he went to the rally site in the morning, was there for an hour, and then left. He came back sometime in the early 5:00 p.m. hour and tried to enter the perimeter at around 5:30.
The motive remains a mystery, according to the briefers, and they have not identified any ideological nexus to former President Donald Trump and or President Joe Biden.
Based on interviews with the shooter's parents, law enforcement told members they believe that neither has strong political leanings.
The FBI told lawmakers they've conducted 200 interviews as part of the investigation, a source said.
Twenty minutes passed between the time USSS snipers first spotted Crooks on the roof and the time shots were fired at the former president, new information shows.
