(CNN)A timeline of Hillary Clinton's email scandal.
2008 -- The server used for clintonemail.com is registered under the name Eric Hoteham. This is presumably a misspelling of Eric Hothem, the name of a former Clinton aide.
2009 -- Government employees are allowed to use private emails for government work. However, this practice is strongly discouraged. If using a private email, "the agency must ensure that federal records sent or received on such systems are preserved in the appropriate agency record-keeping system."
January 13, 2009 -- The domain clintonemail.com is registered in the name of longtime adviser to former President Bill Clinton, Justin Cooper. Hillary Clinton's email is set up as email@example.com
November 2012 -- Clinton's private email server was redesigned to use Google as the backup server.
December 13, 2012 -- Congressional investigators ask Clinton if she uses a personal email.
March 20, 2013 -- Gawker reports that based on emails retrieved by a Romanian hacker called "Guccifer," Clinton used the "clintonemail.com" domain name in emails to advisers and friends. Because her original address is revealed in the article, Clinton changes her email address.
July 2013 -- Clinton's email server is changed once again to be backed up by a McAfee-owned company.
September 2013 -- National Archives and Records Administration clarifies that personal email can only be used in "emergency situations" and that emails from personal accounts should be captured and managed in accordance with agency record-keeping practices.
2014 -- The State Department requests that all former secretaries of state "submit any records in their possession for proper preservation."
Also in 2014, at the request of the State Department, Clinton hands over 55,000 pages — approximately 30,000 emails. Left out were emails deemed by her and her staff to be "personal."
December 1, 2014 -- President Barack Obama signs an update to the Federal Records Act that clarified how private emails are allowed to be used. According to the National Archives and Records Administration, this update prohibits "the use of private email accounts by government officials unless they copy or forward any such emails into their government account within 20 days."
March 3, 2015 -- Clinton spokesman Nick Merrill says:
- "... like secretaries of state before her, she used her own email account when engaging with any department officials."
- "For government business, she emailed them on their department accounts, with every expectation they would be retained. When the department asked former secretaries last year for help ensuring their emails were in fact retained, we immediately said yes."
- "Both the letter and spirit of the rules permitted State Department officials to use non-government email, as long as appropriate records were preserved."
March 3, 2015 -- State Department spokeswoman Maria Harf says: "[There's] no indication that Secretary Clinton used her personal email account for anything but unclassified purposes ... While Secretary Clinton did not have a classified email system, she did have multiple other ways of communicating in a classified manner, including assistants printing documents for her, secure phone calls and secure video conferences."
March 4, 2015 -- After 48 hours of silence, Clinton tweets: "I asked State to release them. They said they will review them for release as soon as possible."
The same day, the House committee investigating the 2012 attack on the US Consulate in Benghazi, Libya, issues a subpoena for Clinton's Libya-related emails.
March 5, 2015 -- It is revealed that Clinton isn't publicly registered as the owner of the domain and server used to operate her personal email. This makes it more difficult to trace the account back to her. Accounts were registered in her aides' names, and she used a proxy company to shield her involvement.
March 6, 2015 -- The State Department begins reviewing emails to determine what can be publicly released, not whether Clinton did anything wrong.
March 10, 2015 -- Clinton holds a 20-minute "press encounter" at the United Nations, saying:
- "At the end, I chose not to keep my private personal emails -- emails about planning Chelsea's wedding or my mother's funeral arrangements, condolence notes to friends as well as yoga routines, family vacations, the other things you typically find in inboxes ..."
- "I opted for convenience to use my personal email account, which was allowed by the State Department, because I thought it would be easier to carry just one device for my work and for my personal emails instead of two."
- "Looking back, it would have been better if I'd simply used a second email account and carried a second phone, but at the time, this didn't seem like an issue."
- Clinton wouldn't disclose how her emails were encrypted, "given what people with ill intentions can do with such information in this day and age, there are concerns about broadcasting specific technical details about past and current practices."
- "I trust the American people to make their decisions about political and public matters, and I feel like I've taken unprecedented steps for these emails to be in the public domain. I went above and beyond what I was requested to do."
March 12, 2015 -- State Department spokeswoman Jen Psaki tells reporters the State Department would remove any emails "deemed not to be agency records."
March 27, 2015 -- Rep. Trey Gowdy makes the statement, "Secretary Clinton unilaterally decided to wipe her server clean and permanently delete all emails from her personal server."
Clinton's lawyer responds in a letter that she "has maintained and preserved copies" of work-related or potentially work-related emails that were turned over to the State Department late in 2014. The lawyer, David Kendall, also stated that federal law governing record retention requires that each federal employee individually decide what emails must be preserved.

July 7, 2015 -- CNN's Brianna Keilar has an exclusive interview with Clinton. In response to being asked about deleting 33,000 emails while under investigation by a House panel, Clinton says other secretaries of state had done the same thing. Clinton also says she was never subpoenaed by the House.

August 15, 2015 -- Clinton makes comments about the scandal at the Iowa State Fair.

August 18, 2015 -- Clinton tells reporters that "nobody talks to me about it other than you guys" in response to questions about her email. She states, as she has before, that she handed over anything that was thought to be work-related.
"Under the law, that decision is made by the official. I was the official. I made those decisions," Clinton says. "And as I just said, over 1,200 of those emails have been deemed not work-related."
August 26, 2015 -- At an event in Iowa, Clinton says, "My use of personal email was allowed by the State Department. It clearly wasn't the best choice. I should have used two emails -- one personal, one for work -- and I take responsibility for that decision." She also adds: "Well, I know people have raised questions about my email use as secretary of state, and I understand why. I get it." This is a change from her previous responses to questions about her email use.

September 8, 2015 -- Hillary Clinton releases an apology and statement on her Facebook page about the email scandal:
"I wanted you to hear this directly from me:
"Yes, I should have used two email addresses, one for personal matters and one for my work at the State Department. Not doing so was a mistake. I'm sorry about it, and I take full responsibility ..."
September 9, 2015 -- During an interview on ABC News' "World News Tonight with David Muir," Clinton says she should have used separate emails for her work and her personal business, and she apologizes for her use of a private email server. She says, "I take responsibility, and I am trying to be as transparent as I possibly can."

"Given the Department's current FOIA workload and the complexity of these documents, it can process about 500 pages a month, meaning it would take approximately 16-and-2/3 years to complete the review of the Mills documents, 33-and-1/3 years to finish the review of the Sullivan documents, and 25 years to wrap up the review of the Kennedy documents -- or 75 years in total," the State Department argued in the filing.

And there are no excuses. I want people to know that the decision to have a single email account was mine. I take responsibility for it. I apologize for it. I would certainly do differently if I could." She adds, "I believe the public will be and is considering my full record and experience as they consider their choice for president."
