They're not all automatically guilty here. Trump is not automatically guilty because some microscopic bit of a random aspect of his portfolio that he doesn't manage, has $99 invested in a company that makes hchloroquine.

Did they make a call and warn their financial managers with inside info? Or, was this normal money management stuff that they're not even informed about? I'd be extremely surprised if these were the only 4 who bought or sold or invested something during that time frame.

I believe more than one of them called for ethics investigation in to themselves. I'm the last person to defend sleazebag career politicians, but I also don't work for CNN.
