The conservative watchdog group Judicial Watch released almost 900 new emails from a Huma Abedin email account on Tuesday, which the group said offer more proof that Hillary Clinton sent and received classified information through her unsecured home server when she was secretary of state. Abedin was a long-time top aide to Clinton.

Judicial Watch obtained the emails with a Freedom of Information Act request that also required a follow-up lawsuit in 2015 after the State Department failed to produce any records.

"These new emails show Hillary Clinton is a serial violator of various laws concerning the handling of classified material," Judicial Watch President Tom Fitton said in a press release. "This new information should spur new federal criminal investigations."

As one example of their claim, Judicial Watch pointed to a 2009 email from then-Secretary of State for African affairs Johnnie Carson in which the final, released version contained paragraphs redacted because of "Foreign Government information."

Another email contained redactions due to "information specifically authorized by an executive order to be kept secret in the interest of national defense or foreign policy."

Other released emails show Clinton emailing her daily schedule to top officials at the Clinton Foundation, the charitable organization led by former President Bill Clinton and his family, which drew enormous scrutiny throughout the 2016 presidential campaign.

Judicial Watch said the emails add to the total number of documents not turned over to the State Department. That runs contrary to Clinton's claim that she believed all of her government emails had been discovered and turned over after it was revealed she had kept an email account that wasn't created and secured by the government.
