Bribery of a Witness (18 U.S.C. Sec.201(b)(3)) is a federal crime that prohibits offering, giving, or promising anything of value to a witness in an effort to influence the testimony of that witness in an official proceeding. It also forbids the retaliation of a witness for their refusal to accept a bribe or to provide false testimony. There are two types of bribery of a witness: direct bribery and indirect bribery. Direct bribery of a witness involves offering, giving, or promising something of value directly to the witness in exchange for their testimony. Indirect bribery of a witness occurs when someone offers, gives, or promises something of value to a third party in exchange for influencing the witness to provide false or misleading testimony. Both types of bribery of a witness are punishable by fines and/or imprisonment.
