A deep fear came to pass for many artists, museums, and cultural organizations nationwide early Thursday morning when President Trump, in his first federal budget plan, proposed eliminating the National Endowment for the Arts and the National Endowment for the Humanities.

President Trump also proposed scrapping the Corporation for Public Broadcasting, a key revenue source for PBS and National Public Radio stations, as well as the Woodrow Wilson International Center for Scholars.

It was the first time a president has called for ending the endowments. They were created in 1965 when President Lyndon B. Johnson signed legislation declaring that any “advanced civilization” must fully value the arts, the humanities, and cultural activity.

While the combined annual budgets of both endowments — about $300 million — are a tiny fraction of the $1.1 trillion of total annual discretionary spending, grants from these agencies have been deeply valued financial lifelines and highly coveted honors for artists, musicians, writers and scholars for decades.
