I admit I don't know much about insider trading laws, but if Sen. Feinstein sold said shares with the expectation that their price would drop based on what she found out, wouldn't that still be insider trading? All it would say is that Sens. Burr and Loefler are better at stock trading than Sen. Feinstein.
The point is, she says her stocks are in a blind trust, and the fact that the stock sales the MSM is point to as "proof" are the opposite of the kinds of moves you'd expect if she was using her insider knowledge to play the stock market kind of hints that's the case. Actually, Gohmert and Johnson's stock moves are similar; the only ones that SCREAM insider trading are Burr and Loefler, because the stock moves they made line up perfectly with the expected fallout of the Coronavirus hitting the market. And then there's Burr being caught telling rich Republican donors that the fallout from COVID-19 was going to be as bad as the Spanish Flu, while telling the public it was a hoax...
Oh, and as pointed out, Loefler's husband is the head of the NYSE. He also made a bunch of questionable transactions around that time... Probably on a tip-off from his wife.
