While grilling Comey last week, Senator Flake asks if the FBI can share their program's polygraph policy.  He complains that the CBO "failure" rate is 65%, and would like to know how the FBI is able to have more favorable results.

Is there such a policy?  How can you have a standard when the "results" can be so subjective?
