Each year, the American Alliance of Museums encourages museums and similar institutions to #InviteCongress to their sites.  This is an annual effort, held in August, to encourage museums around the country to engage with local, state, and federal elected officials and stakeholders by inviting them into the museum.  They even have a wonderful How-To guide to help museums reach out to their representatives.  To learn more, please visit their website here: AAM Invite Congress.
