( The FBI only has 7 days ? )
OK It is logical that FBI + Senate +other checks would have started as soon as she made the accusations. Also, the recent movements of Haspel indicate that some "research" was in hand some days ago, hopefully on this matter. I live in hope that ALL the comms of those involved in any way have already been examined and hence Grassley was comfortable with committing to an Investigation, knowing there was little or no risk.
