Clinton told reporters after a campaign event in New Hampshire she paid Bryan Pagliano for "his technical assistance" in maintaining the private email server she used with her family while she headed the State Department.
"With respect to personal services he provided to me and my family, we obviously paid for those services and did so because during a period of time we needed his technical assistance and I think that's in the public record," she said.
The Washington Post first reported the Clintons paid Pagliano.
ABC News reached out to Pagliano’s attorney Mark MacDougall for comment.
Pagliano started as Clinton’s IT director in 2006. He worked on her 2008 presidential campaign and then became a special adviser to Clinton while at the State Department.
"While we understand that Mr. Pagliano's response to this subpoena may be controversial in the current political environment, we hope that members of the Select Committee will respect our client's right to invoke the protections of the Constitution," Pagliano's attorneys wrote in a letter Benghazi Committee chairman, Trey Gowdy.
