Sydney Leathers is the girl who came forward with more Anthony Weiner sex scandal info.

The woman at the center of Anthony Weiner‘slatest sexting scandal is speaking out today for the first time, in an interview with Inside Edition.Sydney Leathers, a 23-year-old Democrat from Indiana, said she was “shocked” that he “would be so foolish as to do the same thing all over again.”

“He was making these campaign promises that he’d totally changed,” Leathers said of his public persona, “that he was a better man now and had learned from his mistakes, and I am proof that that is not true.”

From her Inside Edition interview:

“I cared about him a lot,” she said in an exclusive interview set to air tomorrow, but admitted she didn’t quite love him at the time. “He was very important to me.”

Leathers says her feelings have since changed, especially after watching the disgraced former congressman at Tuesday’s press conference with his wife, Huma Abedin. “I’m disgusted by him. He’s not who I thought he was,” she said. She also offered Abedin a tear-filled apology.

As Weiner was preparing for his mayoral campaign, Leathers said he asked her to delete their correspondences. “He was trying to be someone he wasn’t,” she explained.

Leathers is one of at least three women Weiner has now admitted to having sexually-explicit correspondences with since his resignation from Congress in 2011. Leathers, an Indiana native, is a 23-year-old former field organizer for the Obama campaign.
