This I what I think, too. Make Pelosi and Schumer defend the indefensible on live TV.
They don't know what he's going to say or do, nor does the MSM. They're one major revelation away from extinction. so any POTUS action is existence threatening to them at this point. Stress levels must be off the charts.
The Hoyer/Schiff shit today is most likely stress related in an attempt to bait POTUS into showing his cards in a tweet retaliation so they can form an appropriate rebuttal. I don't think they have any idea what's coming, so the chances are high they'll look to be out in left field at the start of their response.
