Iowa. Code. Jud. Cond. 51:3.7
Comment
[1] The activities permitted by paragraph (A) generally include those sponsored by or undertaken on behalf of public or private not-for-profit educational institutions, and other not-for-profit organizations, including law-related, charitable, and other organizations.
[2] Even for law-related organizations, a judge should consider whether the membership and purposes of the organization, or the nature of the judge's participation in or association with the organization, would conflict with the judge's obligation to refrain from activities that reflect adversely upon a judge's independence, integrity, and impartiality.
[3] Attendance at fundraising events and volunteering services or goods at or in support of fundraising events do not present an element of coercion or abuse the prestige of the judicial office and are not prohibited by this rule.
[4] In addition to appointing lawyers to serve as counsel for indigent parties in individual cases, a judge may promote broader access to justice by encouraging lawyers to participate in pro bono publico legal services, if in doing so the judge does not employ coercion or abuse the prestige of judicial office. Such encouragement may take many forms, including providing lists of available programs, training lawyers to do pro bono publico legal work, and participating in events recognizing lawyers who have done pro bono publico work.
[5] Judges, as parents, may assist their children in their fundraising activities if the procedures employed are not coercive and the sums nominal.
