A preservation advocacy group filed a federal lawsuit Monday challenging President Trump’s decision to paint the Reflecting Pool on the National Mall bright blue, arguing the renovation violates both historic preservation and environmental statutes.
The Cultural Landscape Foundation, along with its founder Charles Birnbaum, contends that the dark gray basin is integral to the pool’s original design and that coating it in blue paint “alters the historic character” without proper authorization. “The dark grey, achromatic basin was not incidental to the design. It was the design,” the lawsuit states.
The suit, filed in U.S. District Court in Washington, D.C., also seeks an emergency order to halt the project immediately. The group argues that the administration failed to conduct required consultations under the National Historic Preservation Act and did not meet obligations under the National Environmental Policy Act before making changes to the historic property.
The Reflecting Pool stretches from the Lincoln Memorial to the World War II Memorial, reflecting the Washington Monument along its 2,000-foot length—equivalent to 12 Olympic-sized swimming pools. It has undergone several renovations since its dedication in 1922, including a $34 million stimulus-funded overhaul requested by the Obama administration in 2012, and is regularly drained for cleaning.
Trump announced last month that he would coat the pool in “American flag blue,” framing the move as part of broader efforts to beautify the nation’s capital. The president’s motorcade made an unannounced visit to inspect the work in progress.
An Interior Department spokesperson defended the project, saying, “President Trump has done more to make our nation’s capital a shining beacon than any other president in the history of this country.” The statement added that the National Park Service “chose the best company to expedite the repair of the iconic Reflecting Pool ahead of our 250 celebrations. The choice of American Flag Blue will enhance the visitor experience by making the pool reflect the grand Lincoln Memorial and Washington Monument.”
The lawsuit is the latest legal challenge to Trump’s real estate ambitions in Washington. Other projects, including a planned White House ballroom and renovations to city golf courses, have also drawn lawsuits. The president’s broader agenda has been a target of legal action; his recent rejection of an Iran peace deal, for instance, has fueled congressional budget fights and drawn voter backlash that could threaten GOP midterm prospects.
Trump’s decision to paint the pool blue is part of a pattern of asserting executive authority over federal landmarks, a move that critics say sidesteps established preservation processes. The case now heads to court, where a judge will weigh whether the administration can proceed with the paint job while the legal challenge unfolds.
