“Butowski claims that Seth Rich’s father stated “we know what our sons did, but we just want to find Seth’s killer.” To the truth of whether Seth Rich’s father said that, Butowski is a fact witness not using hearsay.”
He’s not “using hearsay”, he is engaging in hearsay. “I heard XXX say XXX” is the definition of hearsay.
It depends on what the statement is offered for. If offered for the proposition that "XXX said XXX" (emphasis on the speaker, not for the truth of what the speaker said), then the statement is not hearsay.
Well it damn sure wasn't Trump or "the Russians".
