D) Extorting manufactured political dirt is not legal foreign policy or use of Congressionally approved funds.
E) Decorated wounded veteran Lt Col Vindman was following proper procedure reporting the call to the NSC's top lawyer.

G) If it is a witch hunt testimony would soon show it. Don't hold your breath.
