Won't be a big deal for who? This is a President siphoning taxpayer money that he doesn't fucking need. After the Trump Foundation, not paying workers and bragging about avoiding taxes, on top of this, this isn't the time to give our president a pass because "it's not a big deal". If you don't hold his feet to the fire now, then you'll be looking at the "big deal" news later.
It will be a big deal if he'll actually be siphoning millions into his bank account like this during his presidency. That he did it during his campaign, that just makes him smart in his eyes.
Hell, I just don't think he's that tone-deaf to keep this racket going when he's leader of the free world. Call me optimistic. The potential for political fallout is likely too large a risk.
