On the administrationbroadly critical

Background

The Center was founded in 1989 by Kieran Suckling, Peter Galvin, Todd Schulke and Robin Silver, and it grew out of efforts to protect species such as the Mexican spotted owl in the Southwest. It became known for using the Endangered Species Act and other laws to sue federal agencies, often forcing species listings and habitat protections. It now reports more than 1.8 million members and online activists, and its revenue has grown from about $20 million in 2017 to roughly $46 million in 2024. It publishes press releases, reports and advocacy campaigns instead of independent journalism, so its material is advocacy and reflects its conservation goals. Supporters credit it with winning protections for many species. Critics, including some industry groups and conservative organizations, say it uses litigation aggressively, and some say it profits from legal-fee recoveries. During the first Trump administration it filed about 266 suits. By 2026 it had sued the current administration dozens of times, including over the Endangered Species Committee, climate rule rollbacks, and records on policies allowing harm to endangered animals. Its framing of administration actions is consistently adversarial.
