Huma Abedin, Hillary Clinton’s longtime aide, left the former Secretary of State’s daily schedule on her bed in her unlocked hotel room during a conference - despite having a ‘burn bag’ for such items, according to recently released emails.

Another 296 pages of Democratic presidential nominee Hillary Clinton's emails were released on Tuesday by Judicial Watch, which is currently suing the State Department under Freedom of Information Act laws in an attempt to recover all of Clinton's emails.

One email revealed that during a conference in Trinidad and Tobago on April 18, 2009, aide Melissa J Lan emailed fellow aide Huma Abedin to ask for Clinton's 'day book binders', which are thought to be private.

Abedin responded: 'Yes. It's on the bed in my room. U can take it. My door is open. I'm in the lobby.Thx.'

Another Clinton aide appears annoyed in one email, after realizing Clinton's schedule was sent to an authorized State Department email address rather than an unsecured, non-state government account.

While it appears Abedin left Clinton's schedule out in the public in 2009, she testified in June that Clinton burned her daily schedules while serving as secretary of state.

'If there was a schedule that was created that was her Secretary of State daily schedule, and a copy of that was then put in the burn bag, that ... that certainly happened on ... on more than one occasion,' Abedin told lawyers representing conservative watchdog group Judicial Watch, according to the New York Post.

While Clinton admitted to deleting personal emails from her homebrew server, this was the first time anyone in Clinton's State Department inner circle admitted to destroying public records while on the job.

The 'burn bag' is used to discard sensitive or classified documents.

A former State Department employee told the New York Post it was unprecedented for a diplomat to handle schedules this way.

'I spend eight years at the State Department and watched as four U.S. ambassadors and two secretaries of state shared their daily schedules with a variety of State Department employees and US officials,' Richard Grenell, a former diploma and U.S. spokesman at the United Nations told the Post.

'I've never seen anyone put their schedule in the burn bag – because every one of them had a state.gov email address and therefore their daily schedules became public records, as required by law,' Grenell added.

Abedin had been asked the question, 'And during your tenure at the State Department, were you aware of your obligation not to delete federal records or destroy federal records?'

The Judicial Watch lawyer did not press her with a follow-up.

The conservative group was given permission to depose Clinton's State Department aides as part of an ongoing Freedom of Information Act lawsuit rooted in Abedin's unique employment setup.

Abedin was allowed to work both at the State Department and for the outside consulting firm Teneo.

She performed duties for the Clinton Foundation as well.

Today she serves as Clinton's vice chairwoman for her presidential campaign.

The Post noted that the Associated Press, in another lawsuit, had been seeking Clinton's schedule from throughout her time as secretary of state, suing for access to those documents in 2015.
