If what I read yesterday was correct, or if I recall it correctly, Cohen and Davis (lawyer) said they worked out an arrangement with Cummings to postpone the testimony. Grounds for postponement were 'threats against Cohen's family'. Most likely, those threats referred to POTUS saying, "they need to look into Cohen's family". That tweet further thanked Cummings for his cooperation.
An hour or so later Schiff & Cummings tweet that the testimony won't be postponed because we're all big and Stuff and this is our show (basically).
Today POTUS says no testimony. So what happened to Schiff and Cummings? Adding to that, why did Cohen & Davis say Cummings allowed the postponement when Cummings and Schiff tweeted later they weren't going to?
Hopefully, this is open mockery of the committee, the tools the dems keep swearing they're going to use against Trump.
Adding to this, I think the, 'look into the family' tip by POTUS was a curve ball Cohen, Davis & Cummings couldn't hit. The postponement was to come up with another plan because the one they had was going to backfire.
