A group of cultural and historical preservation groups filed a lawsuit against US President Donald Trump on Monday to block the further closure of the John F. Kennedy Center, which the president insists is necessary for revenue renovations.

Plaintiffs include the National Trust for Historic Preservation in the United States, Society of Architectural Historians, and the Cultural Landscape Foundation. The lawsuit alleges that President Trump’s recently announced plan to shut the Kennedy Center down for two years to carry out renovations is unnecessary and unlawful. The complaint states that President Trump and the Kennedy Center Board of Trustees seek “[t]o fundamentally alter this iconic property without complying with bedrock federal historic preservation and environmental laws, and without securing the necessary congressional authorization.”

Plaintiffs are calling on the District Court for the District of Columbia to enjoin the plan, citing recent remarks by President Trump and the Kennedy Center Board of Directors which plaintiffs argue imply a large-scale gutting of the center. Plaintiffs say the Trump administration should be enjoined from closing the Kennedy Center until it complies with all of the necessary requirements for conducting a renovation project of this size.

The lawsuit joins several others that challenge President Trump’s plans to renovate other historic Washington, D.C., structures. Most recently, a federal judge denied an injunction request to block President Trump from knocking down the East Wing of the White House to make way for a ballroom.
