Lewis and Leland introduced another bill in 1989. Once more, cost considerations killed the bill. The Smithsonian Institution, however, was moving toward support for a museum. In 1988, an ad hoc group of African-American scholars—most from within the Smithsonian, but some from other museums as well—began debating what an African-American history museum might look like. While the group discussed the issue informally, Smithsonian Secretary Robert McCormick Adams, Jr. publicly suggested in October 1989 that "just a wing" of the National Museum of American History should be devoted to black culture, a pronouncement that generated extensive controversy. The discussions by the ad hoc group prompted the Smithsonian to take a more formal approach to the idea of an African-American heritage museum. In December 1989 the Smithsonian hired nationally respected museum administrator Claudine Brown to conduct a formal study of the museum issue.
