This report was prepared for the Advisory Committee on the Federal Rules of Evidence. Under the current version of Fed. R. Evid. 801(d)(1)(B), prior consistent statements are admissible for their substance as well as for their rehabilitation only if they rebut recent fabrication because they occurred before the fabrication motive. If a prior consistent statement is admissible for credibility but not admissible for substance, the opposing party is entitled to a jury instruction.
