The filing was in response to a lawsuit filed last Friday by the National Trust for Historic Preservation asking a federal judge to halt President Donald Trump’s project until it goes through multiple independent reviews and a public comment period and wins approval from Congress.

The administration’s 36-page filing included a declaration from Matthew C. Quinn, deputy director of the U.S. Secret Service, the agency responsible for the security of the president and other high-ranking officials, that said more work on the site of the former White House East Wing is still needed to meet the agency’s “safety and security requirements.” The filing did not explain the specific national security concerns; the administration has offered to share classified details with the judge in a private, in-person setting without the plaintiffs present. https://apnews.com/article/trump-white-house-ballroom-national-security-de9756118bbfca8f40af9cf89db6af5b
