President Trump threatens a defamation lawsuit against the Center for American Progress over a report on National Guard deployments, while the Supreme Court temporarily allows White House ballroom construction to continue.

Additionally, the CDC links nearly 11,000 cyclospora cases to iceberg lettuce, and a British court orders Prince Harry and others to pay damages in a privacy lawsuit.
