William & Mary Dunn Fellows have assisted a broad array of civil liberties organizations, including the American Civil Liberties Union Foundation (Denver, CO; Washington, DC; Atlanta, GA; Portland, ME; Newark, NJ; Richmond, VA); Americans United for Separation of Church and State (Washington, DC); the Baptist Joint Committee for Religious Liberty (Washington, DC); the Berkman Center for Internet and Society (Cambridge, MA); the Brennan Center for Justice (New York, NY); and the Council on American-Islamic Relations (Washington, DC).
The American Civil Liberties Union is one of the most prominent civil liberties organizations in the country. Its mission is to "defend and preserve individual rights and liberties guaranteed to every person in this country by the Constitution and the laws of the United States." Since its founding in 1920, the ACLU has been heavily involved in civil liberties litigation and lobbying. The ACLU has played a role in almost every major civil liberties case of the last century, including the Scopes Monkey Trial, Loving v. Virginia, Brown v. Board of Education, and Roe v. Wade.
The ACLU has 54 branches throughout the country. In Summer 2011, Dunn Fellows and law students Sedric Bailey, Anthony Balady, Lauren Coleman, and Nicholas Mueller worked at the Georgia and National Capital branches of the ACLU.
The Baptist Joint Committee For Religious Liberty's mission is "to defend and extend God-given religious liberty for all, furthering the Baptist heritage that champions the principle that religion must be freely exercised, neither advanced nor inhibited by government." The organization, though supported primarily by Baptists, advocates for religious liberty on behalf of individuals of all faiths.
The Baptist Joint Committee is involved in religious liberty cases nationwide, often filing amicus briefs in any Supreme Court case implicating religious liberties issues. The Committee is also heavily involved in religious liberty education, holding workshops on the separation of church and state on Capital Hill and in churches across the nation. In 2011, Dunn Fellow Andrew Gardner interned at the Baptist Joint Committee office in Washington D.C..
Americans United for Separation of Church and State is "dedicated to preserving the constitutional principle of church-state separation as the only way to ensure religious freedom for all Americans." The AU works both inside and outside the courtroom to defend civil liberties, attempting first to provide out of court solutions to unconstitutional infringements on religious liberty. If necessary, the AU initiates lawsuits and provides legal counsel to individuals who believe the First Amendment has been violated.In the summer of 2011, the AU hosted Dunn Fellow Ani-Rae Lovell.
