Comer requested an unclassified document--not a redacted one.
Redacting an unclassified document is like redacting a phone book
The only redaction should be the name of the CHS, who is already known to Comer and Grassley.
Since Comer and Grassley have already seen the document, provided by the whistleblower, they will compare the two. Interesting that the FBI has offered to have them review the document in a SCIF. All BS. Comer should continue to demand the entire document.
