NO, NO, NO, NO, NO!
Hutchinson's testimony was two-fold.
a) Her direct testimony was first-hand knowledge, and she comported and explained herself with perfect and corroborated credibility.
b) Her second-hand knowledge was accepted as hearsay. She literally heard what other people said they saw. Hearsay is generally not admissible in a court room but welcomed in an investigation where it can or cannot be corroborated by direct witnesses.
As to Trump, we all know he's a deranged socio/psychopath so predicting his behavior is a fools errand.
Proof of Hutchinson's credibility is the 'Trump Derangement Syndrome' of the Trump sycophants who are hysterically - and failingly - trying to discredit her.
