Now somebody want to explain to me, how a police officer (in the motorcade but not in the President's SUV) could possibly know what went on in the car? Sounds like another Adam 'Shifty' Shiff's double secret witnesses. More hearsay testimony with no cross examination. And anyone consider that if Trump had been allowed to go to The Capitol...maybe things would not have happened.

"A Washington, DC, police officer has corroborated to the House select committee investigating January 6, 2021, details regarding a heated exchange former President Donald Trump had with his Secret Service detail when he was told he could not go to the US Capitol after his rally, a source familiar with the matter tells CNN.
The officer with the Metropolitan Police Department was in the motorcade with the Secret Service for Trump on January 6 and recounted what was seen to committee investigators, according to the source.
The report goes on to say that the committee “is also engaging with the driver who was in the presidential SUV regarding possible testimony.”
