State Department officials will release 1,250 pages of Hillary Clinton's deleted emails Thursday afternoon, amid renewed controversy over the FBI's decision to reopen the investigation into her handling of classified material.

The release Thursday afternoon will mark one of the final batches of emails to emerge before voters head to the polls. These records were uncovered during the FBI's original, year-long probe into the private server network and subsequently turned over to the State Department.

The emails come as Clinton's campaign is still struggling to explain revelations about her email server that contradict the Democratic nominee's past statements.

This time, her campaign's prior praise of Comey has faced renewed scrutiny given Clinton's assertion this week that his announcement was coordinated with congressional Republicans in order to boost Donald Trump.

Most of the FBI-provided emails published by the State Department to date have been nearly identical to the roughly 30,000 emails the agency released in batches from May 2015 to February of this year.

But the FBI uncovered thousands of work-related emails that Clinton did not turn over to the State Department originally.

A court has ordered the State Department to produce those records to the public. However, the judge did not specify when the agency must release the previously-undisclosed portion of that trove.
