18 U.S.C. Sec. 1512(B)(3) states that it is a federal crime to engage in witness tampering. Specifically, it is illegal to hinder, delay, or prevent the communication of information relating to the commission of any federal offense. This includes any attempt to influence, intimidate, or otherwise tamper with a witness, victim, or informant with the intent to impede the communication of information relating to the commission of a federal crime. There are two types of witness tampering violations under 18 U.S.C. Sec. 1512(B)(3): (1) tampering with a witness, victim, or informant; and (2) preventing the communication of information relating to the commission of a federal offense.
