Question.

Question: on: “IMPEACHMENT INQUIRY HEARINGS.” In Capitol Hill …USA.

Why did Donald sent Rudy Giuliani to deal with the government to government help between US and Ukraine?

…if Giuliani is not a diplomat but, a personal lawyer defending an protecting the President, why Donald involved him doing international politics instead of using the diplomatic political and constitutional channels which are USA ambassadors but never a personal lawyer of which constitutionally has not right to mess around in this Nation State politics?

…if Donald is been observed by member of the US Congress cuz been suspicious of using his presidential power to benefit himself, his family and near acquaintances, why he uses someone not legally assigned to run Presidential errands with another countries?  …but USA Ambassadors?

These questions are based on the “historic first public hearing on two key witnesses face question on pres. Trump & Ukraine in first public hearing”  presented -live- in CBSN, 13 of November @ 12:01 pm.: “IMPEACHMENT INQUIRY HEARINGS.” In Capitol Hill …USA.
The answer is simple: the person assigned to work for US in Ukraine as ambassador, was working by advising that government how to solve that problem and our president could not give direct orders to USA ambassador in committing illegal activities while the ambassador was advising that nation not to do illegal acts so that nation could stand up and protect its land against foreign intervention with the intention of usurp more of its territory.  US president saw an opportunity in using that land in crisis as a trampoline to win future elections in 2020 by playing dirt against one opposition ...so he sent his own confidant to do the work, and possible it was him who gave him the idea.
