The FBI has sent investigative materials into former Secretary of State Hillary Clinton's use of a private email server to Capitol Hill, including notes from the Bureau's interview with Clinton, it was reported Tuesday.

CNN first reported during the weekend that lawmakers would soon receive the documents. More from its story Tuesday:

The notes, called 302s, represent an FBI agent's memos on the interviews and will be provided along with other investigative material. The material is designated classified so it will need to be reviewed by congressional officials in a Sensitive Compartmented Information Facility, or SCIF. And due to its confidential status, it cannot legally be shared with the public. "The FBI conducted this investigation, as it does all investigations, in a competent, honest and independent way," FBI acting Assistant Director Jason V. Herring wrote in a letter to House Oversight Committee Chairman Rep. Jason Chaffetz and the committee's ranking Democratic member, Maryland Rep. Elijah Cummings. … The letter also says others who engaged in the same type of behavior as Clinton would be potentially subject to "severe administrative consequences."

Although the material is classified, the Clinton camp said that it would rather have the notes released publicly and in full than "released piecemeal by people with motive."

House Republicans continue to press the case against Clinton. On Monday, House Oversight and Government Reform Committee Chairman Jason Chaffetz and Judiciary Committee Chairman Bob Goodlatte sent a letter to the U.S. Attorney's Office for the District of Columbia outlining "several pieces of Secretary Clinton's [congressional] testimony that appear to implicate … the criminal statutes that prohibit perjury and false statements, respectively."
