ABC’S RICK KLEIN: It’s not “a few more emails,” and it’s a big deal, actually:

“We’ve already released, I don’t know, 30,000 plus,” Hillary Clinton told Jimmy Kimmel Monday, “so what’s a few more?” To answer that question: quite a lot. Clinton’s defense of her own behavior in the never-ending story of her own email server has been built on a few pillars that have shown cracks: that the practice was permitted and had precedent, that she never sent or received classified material, that she released all of her work-related emails. Colin Powell and James Comey have weakened the first two defenses. Now Clinton herself is seemingly acknowledging that there are more emails that weren’t released. That’s actually now already established. The emails disclosed by Judicial Watch include another 20 involving the secretary of state that weren’t part of the official State Department release, according to the conservative group. Maybe the rest, as Clinton told Kimmel, are so boring as to be embarrassing. But the real embarrassment could be even more disclosures, all the way through October, of work-related emails that Clinton and her team said did not exist.

And what we know is, most likely, just the tip of the iceberg.
