what do you think o steution means you idiot?He did not say there was no obstruction. He said the investigation wasn't stopped, curtailed etc.
He actually said there was obstruction multiple times. If I were you I wouldn't use that link in future obstruction debates because it is very damning to Trump.
What the Dems know or knew is purely speculation.

no speculation. is needed we have the report and his testimony
