Transition team members will avoid both actual and apparent conflicts of interest. More specifically, Transition team members may not participate in any particular Transition matter that they know may directly conflict with a financial interest of the member, an immediate family member, partner, client or other individual or organization with whichthe member has or has had a business relationship within the past 12 months. Even if there is no direct conflict, a team member will bring to the General Counsel’s attention any potential for the appearance of a conflict. An appearance of a conflict exists whenthe circumstances are such that a reasonable person would question the impartiality of a Transition team member or conclude that that member's work on a particular matter would undermine public confidence in the Transition Team.
(At this point the reader should be reminded that nearly all of Biden's picks have these exact conflicts of interest)
