Justice Department lawyers made a rare apology to a federal judge Wednesday for an “inadvertent oversight” that occurred in a freedom of information lawsuit involving President Donald Trump’s Washington, D.C., hotel.

That “oversight” came after the government attempted to withhold the names and email addresses of various Trump transition team members in an ongoing Freedom of Information Act battle against ethics watchdog group American Oversight. Several of those names were already publicly listed on Trump’s website, greatagain.gov.
