Can a Grand Jury be convened to consider indictment the four Senators who dumped stock?

15. That's a bs argument. The timing can always be suspect

If an activity happens often enough, it's easy to precede another event by weeks or months. That's why this cannot be evidence alone. There are other factors that should be taken into account, for instance, as far as I've read, Feinstein wasn't in the briefings about corona that Burr was in. Feinstein's stocks were also handled through a blind trust which typically means she has neither control on when stocks are sold nor does she even know about the details of her investment.
Further, her stocks were related to biotech and in contrast to some Rep Senators, I didn't read anything about her selling stocks that would be hit hard (hotel business) or a reinvestment into areas that could "benefit" from such a crisis. That cannot be said about some of the Repubs

Just making an argument based on timing alone is lazy when so much more info is available. But it's interesting that a couple of BS supporters are so invested into going after Feinstein.
