He's currently running the Trump Organization. How could he not know about it?
He was asked “last year”...so maybe something occurred since “last year” that forced the issue and the secret service had to pay. Like the the G7 or other type summit Trump wanted to host at his own resort for nothing but there was such a hue and cry about “enoluments and Trump getting some such “free publicity,” from the Dems that he ultimately wasn’t allowed to host the summit. This secret service issue may be tied to something like that.
This giving secret service cheap accomodations could be twisted as some sort of “bribe” to provide more “services” beyond the SS’s mandates. I’m sure it is not but, you know the impeach happy Dems!
