Not that it matters anymore at this point
Sydney Blumenthal sent Clinton "copy and paste" intel on Libya via an ex-CIA guy attempting business deals there. None of these emails were released by Clinton in the original request because she says they were "unsolicited" (despite replies from her to him to continue updating her).
As for providing more emails to the committee, poor Sydney can't, because he said his server was hacked by the ruskies.
At this point, none of them seem to care anymore that they know we know they're lying, since there are no consequences for their actions, other than profitable ones like job offers, book deals, and speaking engagements.
