It’s too bad that Mueller's hands are tied regarding Trumps finances. It's my understanding that his directive is only to determine if Trump et al worked with the Russians during his presidential campaign. And nothing regarding his finances. Is this true? I am unclear on that.
What most Trump detractors really want to know is how deeply he is in bed with Russian and Saudi financiers. Amongst others. Is there any way that complete answers to those questions will ever see the light of day?
Mueller may be constrained, but the US House of Reps is not. They can investigate whatever they want. There appear to be some shenanigans going on in regards to Saudi Arabia's crown prince ordering the assassination of a journalist and it seems to have some financial underpinnings connected to Trump and weapon sales...
But no, Ken, none of it will ever see the light of day.
