Let’s take a look at the timeline of relevant events, according to the FBI report. (The most pertinent information is on pages 15-19 of this document.)
Feb. 1, 2013: Clinton serves her last day as secretary of state.
July 23, 2014: The State Department reaches an agreement with the Benghazi committee about producing records for its investigation into the 2012 attack on a U.S. embassy in the Libyan city.
Oct. 28, 2014: The State Department sends an official letter to Clinton’s staff requesting "emails related to their government work." Clinton’s lawyer, David Kendall, and aide Cheryl Mills oversaw the review of Clinton’s email archives to produce work-related documents to the department.
Dec. 5, 2014: Clinton’s team provides 55,000 pages of emails, or about 30,000 individual emails, to the State Department. Mills tells an employee at Platte River Networks, which managed the server, that Clinton does not need to retain any emails older than 60 days.
March 2, 2015: The New York Times breaks the story that Clinton used a personal email account while secretary of state.
March 4, 2015: The Benghazi committee issues a subpoena requiring Clinton to turn over all emails from her private server related to the incident in Libya.
Between March 25-31, 2015: The Platte River Networks employee has what he calls an "oh s---" moment, realizing he did not delete Clinton’s email archive, per Mills’ December 2014 request. The employee deletes the email archive using a software called BleachBit.
March 27, 2015: Clinton’s lawyers send a letter to the Benghazi committee saying that the State Department already has the relevant emails, as they were included in the Dec. 5, 2014, turnover.
However, the implication — that Clinton deleted emails relevant to the subpoena in order to avoid scrutiny — is unprovable if not flat wrong.
The FBI’s investigation did find several thousand emails among those deleted that were work-related and should have been turned over to the State Department. However, FBI Director James Comey said in a July 2016 statement that the FBI investigation "found no evidence that any of the additional work-related emails were intentionally deleted in an effort to conceal them."
Comey added in a later congressional hearing that the FBI learned no one on Clinton’s staff specifically asked the employee to delete the emails following the New York Times story and subpoena. Rather, the employee made that decision on his own.
Clinton told the FBI that she did was not involved in deciding whether individual emails should be sent to State Department, nor "did she instruct anyone to delete her emails to avoid complying with FOIA, State or FBI requests for information."
