Releasing bad news or documents on a Friday afternoon in an attempt to avoid media scrutiny is often called a “Friday news dump” by members of the media.

NPR: “Often, the White House sets the release of bad news and unflattering documents to late Friday afternoon. The Pentagon and other agencies also use the practice, a legacy of earlier administrations.”

The television show The West Wing had an episode on the technique called, “Take Out the Trash Day.”
