National park signage

BOSTON — The First Circuit stayed a Massachusetts federal court’s preliminary injunction blocking Donald Trump’s executive order titled “Restoring Truth and Sanity to American History,” which required the National Park Service to flag or remove park materials “addressing climate change, slavery, abolition, immigration, labor, women’s suffrage, civil rights, and the culture and mistreatment of indigenous groups.” The conservation group that sued could not show how they are likely to suffer irreparable harm absent the injunction.
