No quid pro quo. It didn’t come up between the President and Sondland. At least as far the aid stuff went.
If I heard this hatchet job correctly, Sondland said he did not know if the
support funds were held up because of Burisma / Hunter Biden ? It has already been established that Trump had otherwise valid reasons to withhold the money .and the funds were paid promptly and no investigation of Biden was ever consummated.
