Washington is co-chair with Charles Segars, the CEO of Ovation, the arts television network, of this year’s Arts Advocacy Day, to be held April 5.

The effort concentrates on lawmakers on Capitol Hill, where this year many conservative members are calling for an end or sharp decreases in funding for the National Endowment for the Arts and other cultural organizations. The day of lobbying is sponsored by Americans for the Arts, the 50-year-old organization that serves the broad arts community.
