State Department officials are set to publish up to 350 pages of Hillary Clinton's deleted emails Friday in what will be the final batch of her records released before Election Day.

The release will come amid intense scrutiny over the FBI's decision to reopen its investigation of Clinton's emails, which FBI Director James Comey had previously closed in July.

It will mark the 19th time the State Department has posted a tranche of her emails on its public website, a process that became a monthly ritual from May 2015 to February of this year.

During that period, the agency released roughly 55,000 pages of emails culled by Clinton's legal team and turned over to the agency in Dec. 2014.

But the emails set for publication on Friday were not included in that batch. The emails in the State Department's final release were recovered by the FBI during its year-long investigation after Clinton's team deleted them.

"Tomorrow we're required to process 350 pages of emails, and we expect to meet that requirement as well," State Department spokesman Mark Toner said Thursday during the agency's daily briefing.

A court ordered the State Department to process those pages through a Freedom of Information Act lawsuit filed by conservative-leaning Judicial Watch. The watchdog group has forced the agency to produce a number of records that have been key to exposing some of Clinton's most questionable relationships with donors to her family's foundation while she served as secretary of state.

Clinton's treatment of Clinton Foundation contributors has spawned a far-reaching FBI probe into allegations of quid pro quo. The investigation has reportedly grown to include lines of inquiry in New York, Washington, D.C., Little Rock and Los Angeles.

Faced with a late surge from Donald Trump and a flurry of FBI leaks that suggest she and her aides could soon face serious legal consequences, Clinton has accused Comey of politicizing his bureau in order to damage her presidential campaign.

In the days since anonymous agents began telling media outlets about the scope of several criminal investigations into Clinton and her associates, the Democratic nominee has quietly stopped her public calls for Comey to make public his latest findings.

Comey announced on Oct. 28 that his agents had discovered a tranche of "pertinent" emails in an "unrelated" case, which prompted him to reopen the original email investigation.

The unrelated case turned out to be a sexual misconduct investigation of Anthony Weiner, the disgraced former congressman and estranged husband of Clinton aide Huma Abedin.

Abedin reportedly shared at least one device with Weiner that agents seized as part of their probe into allegations that Weiner exchanged sexually charged messages with an underrage girl.

The FBI obtained a search warrant over the weekend for Clinton-related emails from the Weiner device. Those records reportedly date back to her tenure as secretary of state, raising fresh questions about whether she and her aides turned over all official records to the State Department before testifying under oath that they had done so.

The State Department's series of email releases cast a pall over the early months of Clinton's campaign. As the monthly document dumps provided fodder for never-ending stories about the parallel email and foundation controversies, the spectre of a late primary challenge from Vice President Joe Biden fueled speculation that Clinton was a weak candidate for her party's nomination.

Biden withdrew from contention shortly after Clinton ended one of her most persistent scandals by delivering strong testimony before the House Select Committee on Benghazi.

But her Clinton Foundation controversy and email scandal have never relented, and both threaten to follow her into the White House should she defeat Trump on Tuesday.

With tensions between the FBI and the Justice Department over how to handle the Clinton cases spilling out into the open, one side of the law enforcement community is likely to be outraged at the resolution of the dual investigations.

And although the State Department's release Friday will be its last before Election Day, Clinton faces the certainty that thousands of additonal deleted emails will emerge through FOIA litigation that will require the agency to publish the records on a monthly basis beginning in December.
