Stop Senators' insider trading

I've been hearing reports about Senator Burr and Senator Loeffler selling and/or buying stocks after receiving a closed briefing from health officials. edit In addition, Sen. Burr apparently gave remarks to a luncheon of "well connected" people in which he portrayed the corona virus threat in more dire terms than his public comments. Apparently both also sold many blocks of stock (small lots apparently so the size of the transactions would not attract attention). I think there needs to be an investigation of both of them and probably Mr. Trump and his family. The investigation probably needs to start in the House, as I doubt that AG Barr or Moscow Mitch will be willing to do anything. The swamp just gets murkier and murkier.
