The FBI has sent Congress documents related to its investigation of Hillary Clinton's use of a private email server during her tenure as secretary of state.
The House Oversight Committee said Tuesday it had received the documents, marked "secret," which include notes on FBI interviews with Clinton and other witnesses during the investigation.
The Federal Bureau of Investigation closed its yearlong probe last month into whether Clinton and her aides mishandled sensitive information that flowed through the private email server located in the basement of her New York home.
At the time, FBI Director James Comey said his agents found no evidence of criminal wrongdoing by the Democratic presidential nominee. He called her actions "extremely careless," but said no criminal charges were warranted.
Clinton's deeds may have been born of ignorance, the FBI director noted. He said she was not "sophisticated" in the handling of classified information, and may not have recognized the symbol in her emails designating classified materials.
After Comey's testimony, the House Oversight Committee chairman, Republican Congressman Jason Chaffetz, said he was "mystified and confused" how the FBI could find that Clinton mishandled dozens of classified documents and then not be criminally charged.
"If your name is not Clinton," Chaffetz said, "or you're not part of the powerful elite, then Lady Justice will act differently. Hillary Clinton created this mess."
Dissatisfied with the FBI's conclusions, Republican lawmakers are continuing to focus on what they say was the Democratic nominee's haphazard handling of email containing government secrets. Republican presidential nominee Donald Trump, currently lagging in opinion polls, also routinely attacks Clinton over her email use.
Clinton faces further political fallout from the email scandal. The State Department has agreed in a court filing to turn over more emails, recovered after Clinton surrendered her private server, to the conservative organization Judicial Watch, which has filed suit seeking access to the messages.
