A scandal is a very public incident which involves a claim of wrong-doing, shame, or moral offence. A scandal may be about a real event, an untrue event (often called a false allegation) or a mixture of both. Something which is a scandal can be described as scandalous.
Scandals may be told by whistleblowers, who have access to secrets and allow them to go public. A well-known scandal was the Watergate scandal, in which US President Richard Nixon was found to be supporting and hiding illegal burglaries.
Sometimes there are scandals surrounding people who work for the president such as during the Grant administration. The Iran-Contra affair was also a known scandal that surrounded Ronald Reagan and his administration. All were not-guilty of the crime.
