The most likely sequencing of the Democrat scheme has always looked to be: (1) Michael Cohen testimony; then (2) The Mueller report.

Cohen is scheduled to testify to Elijah Cummings House oversight committee Wednesday February 27th (10:00am) next week.  Today, predictably, the DOJ announces the Robert Mueller report will be *after* that testimony:

Instead, the Democrats want the report from Mueller, including all the investigative trails that were exhausted, so they can exploit aspects of the inquiry that were not able to be proven, and weaponize “innuendo” and “possibility” for political benefit.
The process they are following is by design:
