I watched the first half hour or so. She held up the page, and down on the bottom of second page was a red rubber stamp CLIENT COPY. And since it was put in reporters mailbox (church lady smirk, how convenient), who would have access to a CLIENT COPY?
I think the IRS, the accountant firm, or Trump. Or maybe Hawaii’s birth registry.
Not the IRS. If it was truly stamped "Client Copy," only Trump or the accounting firm. Or someone (a lender, for example) to whom Trump gave a copy. I think the latter is the most likely.
