Newly released FBI files turned over to the Senate reveal a Snapchat account tied to Thomas Crooks, the man who attempted to assassinate President Donald Trump.
The federal documents turned over to the Senate, first reported by the Crooks' Snapchat account that may not have been recoverable but said there's a "good amount of information in there."
However, Pack said Crooks was likely careful when using an app like Snapchat, since it's not fully encrypted.
"What you do see is a pattern of trying to hide things and using aliases. And, so, if he's taking that much care to publicly not be seen picking up deliveries and those types of things, you have to assume he's probably taken just as much diligence with his social media and with his digital footprint," he said.
FBI Director Kash Patel testified Tuesday at a Senate Oversight Committee hearing that there's no evidence that Crooks was linked to anyone else.
"We found no evidence that that individual was literally even speaking to any other human being other than his parents, who he resided with," Patel testified.
