Maybe McCarthy meant to say the email mess, which has hurt Hillary. Benghazi might come back and hurt her depending on what the deleted emails say, that Hillary said were personal, if there is something embarrassing on Benghazi. If there is, then she is toast. But first the emails need to be recovered, and then released to the extent not personal.
Yes, obviously he meant the email mess, that's why it was never mentioned in the discussion and Benghazi was multiple times, and why he gave credit to the House Republicans for creating the Select Committee on the Benghazi investigation in the same sentence.
He was obviously referring to the email scandal.
