From Wikipedia:

In United States law, a statement against interest is a statement made by a person which places them in a less advantageous position than if they had not made the statement and is, as a consequence, deemed credible as evidence (usually within a legal trial). For example, if a driver in an automobile accident boasts publicly that they were speeding, it may represent a legal admission of liability. It is analogous to the criminal equivalent, the statement against penal interest which is a statement that puts the person making the statement at risk of prosecution. In the United States federal court system and many state courts, statements against interest by individuals who are not available to be called at trial (but not other persons) may be admitted as evidence where in other circumstances they would be excluded as hearsay.
