And, John, I understand the Clinton campaign has responded to FBI Director Comey's letter.

　　JOHN YANG, PBS NEWSHOUR CORRESPONDENT: That's right. As they flew here from Philadelphia, Jen Palmieri, the communications director for the campaign, spoke to reporters. She said, "We have seen Director Comey's latest letter to the Hill. We're glad to see that as we — glad to see as we were that he has found, as we were confident that he would, that he has confirmed that the conclusions that he reached in July, and we're glad that this matter is resolved."

　　We're told that the FBI went through the emails that they found on Anthony Weiner's laptop found that most of the emails were duplicate of emails that Huma Abedin, Weiner's estranged wife, had already turned over to the FBI. This story really through the campaign for a loop when it broke about a week ago and now they are very happy that it's been resolved.

　　STEWART: John, let's talk about the ground game for the next 48 hours for the Clinton campaign. What can we expect?

　　YANG: She's here in Ohio for the second time if three days. She's going to be in Pennsylvania tomorrow for two more visits to make that three stops in that state over the past several days.

　　What they're trying to do here, here in Ohio, a poll came out this morning showing it a virtual tie — Clinton ahead by one percentage point. They're trying to gain ground in this swing state, this state that no Republican has ever gotten to the White House without first winning this state.

　　Pennsylvania is a state that they are self confident all along but it seems they're trying to nail it down, protect what they all their fortress in Pennsylvania, trying to keep it Democratic, keep it from flipping to the Republican Party for the first time since 1988.

　　STEWART: John Yang reporting from Cleveland, Ohio — thanks so much.

　　YANG: Thanks, Alison.
