The White House will probably tell Congress on Friday that President Donald Trump has approved the public release of a Republican congressional memo alleging FBI bias against him, likely without redactions, a White House official said on Thursday.

The sense in which most people currently use redaction is “an act or instance of redacting something” (employing the sense of redact defined as “to select or adapt, as by obscuring or removing sensitive information, for publication or release”). The word comes from the French rédaction, which is itself from the Late Latin redactio- (“act of reducing, compressing”).
Both redact and redaction have somewhat more obscure senses, which are more concerned with editing, or preparing for publication, than they are with removing sensitive information.
