They don't need Carter Page's testimony/opinon/observations/feelz. They don't need any of what he has to contribute. It's all on paper already. All documented. Who said/did what/when/where. That's all Durham needs and he's got it.
Carter's testimony is just chaff at this point. Superfluous. Durham has them dead to rights.
It's all on paper/documented and there's no way out.
PROPER FUCKED.
(((besides, questioning Carter (who is/was an admitted C_A asset), would open to possible leaks. Not going to risk that unnecessarily. Hence, Carter is left alone.)))
STEALTH.
