FBI agents provided the House Oversight and Intelligence committees a "number of documents" on Tuesday related to their investigation of Hillary Clinton's private email use.

The records were marked "secret," the second-highest level of classification given to government documents, an Oversight Committee aide told the Washington Examiner.

"Committee staff is currently reviewing the information," the aide said in a statement.

Rep. Adam Schiff, ranking Democrat on the intelligence panel, said his committee had received notes from several witness interviews conducted in the course of the FBI investigation — including the three-hour interview with Clinton herself. Schiff said the production also contained "other materials from the FBI's now-closed investigative file."

"With the exception of the classified emails that had been found on the private server, I can see little legitimate purpose to which Congress will put these materials," the California Democrat said. "Instead, as the now-discredited Benghazi Committee demonstrated, their contents will simply be leaked for political purposes."

A Justice Department letter to Rep. Jason Chaffetz, chairman of the Oversight Committee, and Rep. Elijah Cummings, the panel's ranking Democrat, described the records only as a "document production" and did not specify whether the files provided to the Oversight Committee included the notes from the FBI's interview of Clinton.

Clinton's meeting with the FBI in early July was not transcribed nor taken under oath, FBI Director James Comey revealed to the committee last month.

The Justice Department letter noted that while Clinton's careless treatment of classified material did not warrant criminal charges, "this is not to say that someone else who engaged in this type of conduct would face no consequences for handling classified information in a similar manner."

A State Department spokesman said Tuesday that his agency had requested a copy of the notes from Clinton's interview with the FBI before those records were provided to Congress, but was not able to reach an agreement on doing so.
