The president took on a vanity project, gave no-bid contracts to contractors who screwed it up, made up a story about vandals to cover it up, and then fomented a felony prosecution against an innocent scapegoat.

When you slow down and think about it you realize it's ten times worse than it seems. Sure it's farcical, but it's also a brutal legal attack on a man they knew to be innocent, done to distract from their own thievery and incompetence and as a flex to terrify anyone who might make them look bad.
