A "lid" is a term used in politics 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 White House press secretaries use it to indicate that there will be no news coming out of the White House that day, and it can also be called a "full lid". A lid can be called at any time, and it 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, the lid 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.
