Possible extradition of Assange.
It started on Thursday afternoon when Jake Sherman of Politico cited flight tracking information which revealed that someone flew the DOJ G5 from DC to London Tuesday. Ken Dilanian of NBC News then added that It actually took off from Manassas, which is where [the] FBI stations folks who go overseas to grab fugitives. This led to questions about whether perhaps the plane had been dispatched to pick up Julian Assange, who has been in the basement of the Ecuadorian embassy in London for several years. Thats when WikiLeaks spoke up about the flight.
Just minutes after Sherman and Dilanian posted their tweets, WikiLeaks began using its Twitter account to make a lot of noise about the flight. WikiLeaks tweeted A rarely seen US Department of Justice jet N996GA flew to London on Tuesday and has not been recorded as leaving. It then added The plane was noted rendering alleged Russian hacker Yevgeniy Nikulin, to the US, from the Czech republic last year.
