One would hope so. When I worked for Bank of America, as a lowly computer programmer I was required to make all of my investment information available to the compliance office as well as all of my wife's. In practical terms it meant moving my IRAs from Schwab to Fidelity, but it was still inconvenient (and cost me about $100 in fees for which I wasn't reimbursed). I would expect much stricter controls on people with this level of influence.
Disclosure responsibilities for Federal judges extend to spouses and any family living in the home IIRC, I would imagine this restriction would have similar coverage.
