Impeachment *is* indictment. If Mueller does go the "report" route, it
hopefully will be revealing and devastating enough to finish Trump
politically, even if Trump is not impeached by his buddies in the GOP
house. If the Republicans lose the house this fall, impeachment will be
on the table and there will be reopened investigations that will be for
real, instead of the sham investigations the GOP-run committees ran.
A POTUS can be impeached but not convicted as in the case of Bill
Clinton. In fact, he was acquitted.
