Cui bono?

Lev Parnas has a sordid song to sing,
about who stands to lose, and who to gain;
How Trump aspired to make himself a king
extorting criminal help from Ukraine.
Corrupting policy for private ends,
Trump knew Zelensky's up against a wall.
What only Congress has the right to spend
Executives must break the law to stall.
Yovanovich, and Taylor can attest,
Trump held back aid for private benefit.
What Congress meted out is no 'request';
Trump's duty-bound to see Ukraine gets it.
The "drug-deal" Bolton's eager to disown
was documented on Trump's mobile-phone.
