As noted earlier in this thread, both Engel and Ornato have already testified before the Committee, just that this particular incident was not raised. So the notion that they are reluctant to testify under oath is false.
TBH, I don’t get why the fact that Trump REALLY wanted to go to the capitol is such a big deal. He publically said he intended to go. What exactly is added by finding that he “REALLY wanted” to do exactly what he said he would do?
If you ask me, the real irony of the whole thing is that Trump lunging at the driver is actually something you could easily imagine him doing. It’s not such a far-fetched story, based on his temperment and character. The significance of it being most likely false is in what it says about the reliability of Hutchinson’s testimony, and - more importantly, IMHO - what it says about the Committee’s MO.
