The government calls Steve Dejong, with Neustar Security Services

Questioning again for him is starting out technical. He talks about DNS data and what kinds of services his employer provides and what it does with DNS data etc

Steve De Jong says Rodney Joffe, who was Neustar's chief tech officer, in Aug/Sept 2016 asked him to run a query over DNS data to look for names related to political campaigns and political organizations

He said he "didn't think anything of it" at the time. Research is requested all the time, he said.

De Jong says he ran a script to conduct the searches requested by Joffe and sent it off

De Jong said he never got any insight into why Joffe wanted it. "It's not my business," he said.

De Jong said he never heard whether Joffe shared this project with the government or anyone else. "No," he said.

Charlie Savage @charlie_savage · 11m Replying to @charlie_savage DeJong says Joffe & GA Tech researcher Antonakakis asked for searing Neustar's DNS data for long list of Trump & Alfa domains. He pulled logs back to June '16. (Recall Hellman finding it "conveniently coincidental" that traces seemed to begin just 6 weeks before the study.)/43

Bosworth briefly questions De Jong. Establishes that Joffe is respected DNS expert and worked with government/FBI, won FBI award. Sussmann had nothing to do with pulling and analyzing the DNS data. And we're done for the day./44
