This will drag out past the 2020 elections. Only then will Justice be able to get around to the Clintons and Obamas, and Jarretts.
A Federal investigation might, but things are moving much more quickly in other areas because there are ongoing criminal cases here. Someone charged with a crime is guaranteed a “speedy” trial by law, so these cases proceed much faster than others. I believe trial dates have already been set for Paul Manafort and Concord Management, for example.
