The AFM initiated a grass-roots campaign to encourage House members to support the amendment, saying its members sent hundreds of letters to members of the House of Representatives.

In a statement, AFM president Thomas F. Lee said, "thanks to the support from working musicians, congress recognized the valuable contribution that the NEA makes to society and rededicated itself to supporting the arts, Without the fervent support of AFM members, the passage of this bill would not have been possible."

The relationship between the NEA and the government hasn't always been so smooth. The organization was strongly criticized in the 1980s and 1990s for supporting artists such as controversial photographer Robert Mapplethorpe and artist Andres Serrano, which resulted in budget cuts.

But the Washington Post reports that during during a speech celebrating the NEA's 40th anniversary, chairman Dana Gioia said the organization has reconciled with the government. Military bases are now included in NEA outreach programs. "We brought 24 opera companies on tour of 39 military bases," Gioia said.

The American Federation of Musicians of the United States and Canada represents the interests of professional musicians in negotiating agreements, protecting ownership of recorded music, and securing benefits such as health care, among others.
