An ''assertive statement'' is generally defined as the intentional communication of fact. Under the Federal Rules of Evidence, an assertive statement can be oral, written, or non-verbal conduct if it was intended to be an assertion. However, any verbal or non-verbal conduct that was not intended to communicate a fact will not be considered an assertive statement.
