That's not true.
Bobby Engel, top dog secret service guy in the car, already testified before the committee that he and Trump argued in the Beast leaving the Ellipse.... or had a "disagreement" on going to the Capitol, and said he brought him to the Whitehouse instead. This testimony was taken long before the Hutchinson testimony the other day.
What was reported on it was that they had a "disagreement".... but none of his actual testimony or anyone's that testified, has been released....not even to DOJ who had been asking for all the testimony from the committee.
And don't forget,
TRUMP HIMSELF said in an interview, he wanted to go to the Capitol so badly, but Secret Service WOULD NOT LET HIM.
