Clinton, front-runner to be her party's candidate in November's general election, has faced questions about her emails since it emerged a year ago that she used a private email account and a private server during her time in the post from 2009-2013.

Clinton has apologized for the email arrangement, which is being investigated by the Federal Bureau of Investigation, but has said she did nothing wrong and believes the government will vindicate her.

Under scrutiny for her handling of the Benghazi attacks and her use of a private e-mail server, Clinton plans to invoke the memory of slain U.S. ambassador Christopher Stevens to defend her approach to diplomacy, saying they shared a common belief in the need for America to lead.

Stern School of Business in New York on July 24, 2015. The Justice Department said it had received a request to probe whether Hillary Clinton mishandled sensitive government information by using her private email for State Department business. 'The Department has received a referral related to the potential compromise of classified information,' a department official said in a brief statement that confirmed in part a story that first appeared in The New York Times.

The RNC said it filed the lawsuits after the State Department failed to respond in a timely manner to a Freedom of Information Act request submitted in December. It sought the information to ensure the public has information to decide if Clinton is "fit to serve" as president, the RNC said in a statement.

The first lawsuit seeks emails, BlackBerry Messenger or text messages between then-Secretary of State Clinton and several key senior aides, including her chief of staff, Cheryl Mills, and director of policy planning, Jake Sullivan.

The second lawsuit seeks emails and other electronic exchanges between nearly a dozen State Department officials and any Clinton associate using one of more than a dozen different internet domain names. It covers the period between Feb. 1, 2013, when Clinton left the job, and Dec. 4, 2015.

The request includes any emails to the State Department officials from Clinton's campaign website, HillaryClinton.com, or the website of former President Bill Clinton's foundation, ClintonFoundation.org.

The suit also targets emails from domains like MediaMatters.org, a liberal non-profit group that seeks to counter what it believes is misleading conservative information in the U.S. media. (Reporting by Doina Chiacu; Editing by David Alexander and Frances Kerry)
