In 1989, the National Social Action Commission instituted Delta Days in the Nation's Capital, an annual legislative conference to increase members' involvement in the national public policy-making process. The annual conference includes legislative briefings, issue forums, and advocacy skills development. Featured speakers include key policymakers, members of the United States Congress, Congressional staff members, and national issues experts.

The activities of Delta Days in the Nation's Capital are briefings on legislative issues that impact the African-American community; skill development sessions such as How to Advocate Effectively, Understanding the Role of Congressional Staffers, How to Monitor and Track Legislation; and legislative visits to members of Congress. The participants, who come from all geographical areas of the country, also have opportunities to observe the legislators in session, participate in Senate Press Tours and White House briefings. Members of Delta and others with expertise on various issues, conduct the skills development and discussion sessions. In addition, the members also participate in the Congressional Black Caucus Foundation’s Town Hall Meetings and conduct Delta Days at the State Capitol, Delta Days at City Hall, and Delta Days at the School Board.
