President Donald Trump has said he will take a legal dispute over his planned White House ballroom to the Supreme Court after the D.C. Circuit upheld a lower-court decision against the project. Two legal experts told Fox News that opponents may face a difficult argument because the Supreme Court could resolve the case on standing without deciding the wider constitutional question.

The article says Trump made the pledge in a lengthy social-media post on Friday. It presents the ballroom as the subject of a continuing construction and legal battle, with former administration official Stephen Miller describing the facility as a national-security necessity.
