(CNN) Anthony Weiner, the embattled New York City mayoral candidate who admitted this week to sending raunchy chats to a young woman last summer, estimated Thursday he had online relationships with three different women after his 2011 resignation from Congress.

But speaking at a news conference, the Democrat said he couldn’t say for sure how many more women might come forward.

“There are a few. I don’t have a specific number for you,” Weiner said. “There are people I’ve had exchanges with that are completely appropriate, and that there are no pictures or illicit texts or anything. Now if those people want to say they don’t like the exchanges we had either, I don’t know where to put them.”
