It is a rewrite of history.
Any person making testimony before the USA House or Senate needs to have rock solid proof of any statement they make, should never provide opinion outside of that proof and must use the 5th Amendment at every opportunity.
The USA House and Senate Committees will have their own facts. In the case of someone like Hunter Biden they will state he is perjuring himself and look to issue warrants and make arrests for factless reasons.
No one should ever compromise themselves under the returning Trump administration. It is and will be perilous.
