The House select committee investigating the deadly 2012 attack on the U.S. consulate in Benghazi, Libya has said that the State Department pledged to turn over 5,000 documents related to the attack on Tuesday. 

In a statement late Monday, committee chairman Rep. Trey Gowdy, R-S.C., described the document production as "second largest production the Committee has received and the largest since last summer." In return for the documents, Gowdy said he had accepted a request from Secretary of State John Kerry's chief of staff, Jon Finer, to postpone a scheduled Wednesday hearing at which Finer was due to testify.

However, Gowdy warned that a hearing on State Department compliance with the committee's requests would be scheduled if, "the State Department does not fulfill this production, or if production continues to be anemic and underwhelming."

According to Reuters, the documents are not expected to deal with emails sent by then-Secretary of State Hillary Clinton about the attack, which resulted in the deaths of U.S. Ambassador Chris Stevens and three other Americans. Gowdy has repeatedly requested more documents related to Clinton and her staff in the days before the attack. 

Clinton's use of a private e-mail server while in office as America's top diplomat has been a key point of contention between Republicans and Democrats on the committee. On Friday, government investigators disclosed that they had recently alerted the Justice Department to the potential compromise of classified information from Clinton's server.

The next day, a spokesman for the Democrat's presidential campaign, Nick Merrill, said she would testify in a public session Oct. 22. However, committee spokesman Jamal Ware said later in the day that the committee and Clinton's lawyer were "still in negotiation" and nothing has been finalized.
