Stop Lying and just Reject it @SenAdamSchiff 

Legal Precedent:
Burton v. U.S. (1906): the Supreme Court held that acceptance by the person pardoned is #necessary for a pardon to be effective.

Rejection: 
If someone rejects a preemptive pardon, they are essentially not accepting the "#deed" of the pardon. Meaning the pardon does not take effect, as per the legal requirement of acceptance.
