Commentators predict the next chapter of the Department of Justice’s Russia investigation at their peril, but there is good reason to expect one or more blockbuster developments in the next few weeks.

For the record: An earlier version of this article gave the incorrect first name of political commentator Jerome Corsi, as Joseph.

Mueller already has done the difficult digging on the Russian side of the equation, bringing detailed indictments in February 2018 for a wide-ranging Russian trolling operation related to the campaign, as well as the July 2016 hacking of Democratic Party emails. Now he’s looking to tie those allegations to people close to the Trump campaign.
