In politics, a "lid" is a term used to indicate that there will be no more news coming out of the White House or a presidential campaign that day. It is a courtesy announcement to reporters that they should not expect public events, press briefings, or photo opportunities. The term can be called at any time and reflects the complex relationship between the White House and the press. Calling a lid does not necessarily mean that the Presidents workday is over or that no more newsworthy events will happen that day. The President may still have private meetings, phone calls, or other activities that are not open to the press. Additionally, a lid is not an absolute guarantee, and in rare circumstances, it may be lifted if there is a significant event or development. The practice of calling a lid allows the President and their staff to work without constant media scrutiny, and certain activities and discussions need to remain private for reasons of security or diplomacy. The term has been around for decades, but it was popularized by fictional Press Secretary C.J. Cregg on TV show The West Wing.
