FBI Director Christopher Wray offered new details about the explosive devices found in Thomas Matthew Crooks' car and home during testimony before the House Judiciary Committee on Wednesday.
Wray faces questions from lawmakers about the FBI's investigation into Crooks' attempted assassination of former President Trump at a campaign rally in Butler, Pennsylvania.
Here are the key details Wray offered regarding the explosives.
The FBI found three “relatively rudimentary” devices:
Wray says investigators have so far found three explosive devices they believe belonged to Crooks. Two of them were found inside Crooks' vehicle near the Butler rally and one was found inside his home.

Wray described the bombs as “relatively crude” but added that they still posed a significant threat.
The bombs were rigged to detonate remotely:
Despite the crude nature of the explosives, Wray said they were prepared for remote detonation.
Wray did not offer details about the range of the remote detonators, but said it does not appear Crooks attempted to activate them before he was killed by Secret Service snipers.

The thieves had the detonator on the roof:
Crooks had the remote detonator for the explosives with him on the rooftop when he opened fire on Trump.
Wray did not detail the size of the detonator, but said Crooks was able to bring it with him to the roof along with his rifle. The FBI director said the condition of the detonator's on-off switch indicated it would not have worked if Crooks had tried to set off the bombs after opening fire on Trump.
The criminals used encrypted messaging applications:
Wray confirmed that the FBI gained access to Crooks' phone, but said its efforts were hampered by Crooks' routine use of encrypted messaging apps.
Wray said the investigation has not ruled out the possibility that Crooks was working with one or more accomplices.

He said both the drone and the controller were in Crooks' vehicle at the time of the shooting.
Investigators believe Crooks flew the drone near the rally site between 3:50 p.m. and 4 p.m. on the day of the rally. The drone was about 200 yards (180 meters) from the scene during the flight.
