Ye olde Gift Rules of the House of Representatives.
Including golden oldies like House Rule 26: “[T]he restrictions of the gift rule do not apply to “[a]nything for which the [official] pays the market value” (clause 5(a)(3)(A) of House Rule 26). Accordingly, there can be an improper gift to a Member, officer or employee where, for example, he or she is sold property at less than market value, or receives more than market value in selling property.”
