Why? Why? Why?

Mr. Mueller is going to Washington shortly, there to testify about the report he spent two years and several millions of dollars compiling.  I do not know why he is bothering; it will be hot and humid in Washington—it always is this time of year—and it is not as though Mueller will add anything new and significant to what the report says, but the Democrats want to hear this straight from him and Mueller will indulge them.  The Democrats want this more than Mueller does, I suspect.  Since the release of the Mueller Report, the Democrats have been acting like a little girl who wanted a pony for Christmas and is now livid that she did not get one. The little girl was so certain of her getting that pony that she simply dismissed any idea that it might not happen, despite her parents telling her over and over again that there was no room in the apartment for a pony. And then Christmas came and reality, as is its wont, came crashing in with it. Little girls, of course, can only throw tantrums and then sulk in their rooms for days over the crushing of their equine dreams; the House Democrats can throw a tantrum and then subpoena Mr. Mueller and anyone else the House Democrats deems necessary to appear in front of their committees. Someone must explain to Congressmen Schiff and Nadler why President Trump is still President of the United States.  After all, getting rid of President Trump was why Mr. Mueller and his staff got their jobs in the first place.  So why is he still occupying the White House and doing things that the House Democrats find distasteful in the extreme?  Inquiring minds in the House of Representatives want to know, dammit!
