Trump Considers Prosecuting Mueller

This is fairly old news by now, but I don’t see it getting a lot of attention, which surprises me.  It was buried in an NBC article about the State of the Union on January 30, and then a week later, Josh Marshall highlighted it on his site.
But this is astonishing.  There have been a lot of stories about Trump potentially firing Mueller, which is already obstruction of justice, but frivilously prosecuting Mueller seems worse by an order of magnitude, and also brings abuse of power into the mix.

I may be naive, but it seems to me that the media should be asking every member of Congress about this story, and getting them on the record as to whether they consider it obstruction of justice and abuse of power and — if they DO — how they justify going about the business of passing spending bills instead of impeaching Trump, or at least holding a hearing or two.
