There is far far more to the Ukraine/Burisima scheme than the Bidden connection...... for thought.
Burisma was a holding tank with a pipe to the Ukraine money pot. From Burisma, there was a valve controlling the flow and a large diameter pipeline. Corporate directors and their lawyers operate the numerous valves
From that point the plumbing becomes a very complex interconnection of manifolds with smaller valves connected to smaller diameter pipes that connect to banks scattered all over. There might be a concentration of small pipes leading to banks and corporations in say Switzerland or Lichtenstein or Panama.
Those banks say Barclays or DeutschBank or a Swiss boutique bank in Zurich hold the accounts of holding companies with downstream small diameter valves and pipes to yet other corporations.
If we select a person, Barack Obama or his daughter, they would bill a designated company for some service and receive money in a bank issued to that bank account in say the Cayman Islands. These days, that money transfer is likely electronic with no actual paper check.
Both Barack and his daughter have Mastercards issued by the offshore bank used to make purchases within the boundaries of the USA. Monthly on standing direction, the bank pays the outstanding MasterCard bill from funds on foreign deposit. The money never actually travels to the USA. Rather, debits and credits are made on bank ledgers located who knows where.
In the case of Malia, Michelle would direct her offshore lawyer to fax (perhaps e mail) her Cayman Islands company to arrange a payment by certified check from the US branch of the Cayman Islands bank in the amount of her semesters tuition directly to the university bursar.
At every valve there is a lawyer
It may also be that Burisma being an international corporation may also have an inlet pipeline connected to pipes with a money flows from outside the Ukraine.
For instance, there might be pipes connected via various banks and pipes and valves to the us treasury. That is, money from the treasury appropriated for shovel ready jobs in say Philadelphia or green energy in Soylandra could flow to the Burisma holding tank for distribution.
The President knows and understands all the mechanism. The DOJ likely has what amounts to PIDs,Piping and Instrumentation Drawings, of the vast corruption array.
The Democrats and their Iranian allies know that and are doing their dam-nest to get rid of him
Very clever of you to use a common analogy to explain what is a very complex process used by the ruling elite to obscure their ill gotten gains.
