Clinton claims she 'can’t recall' details about private email server

US Democratic presidential nominee Hillary Clinton says she does not remember details about her use of a private email server for government business when she was secretary of state.

Clinton provided little information Thursday on her use of a private email server in a court-ordered response to 25 detailed questions by a conservative government watchdog group.

Clinton submitted written answers under oath through her attorney, David Kendall, in a Freedom of Information Act lawsuit by Judicial Watch in Washington.

The testimony marked the first time Clinton was forced to answer questions under oath about her private email system.

Clinton claimed she does not recall ordering US State Department emails to be deleted from her personal server after she left her post in 2013.

“Secretary Clinton states that she does not recall considering factors other than convenience in deciding to use a personal e-mail account to conduct official State Department business,” Kendall wrote.

“She believed that her e-mails with persons with state.gov e-mail accounts were already captured in the State Department’s recordkeeping systems. Secretary Clinton does not recall anyone from the State Department asking her for access to her clintonemail.com e-mail account or asking her to print her work-related e-mails when she was preparing to leave office,” he added.

Kendall wrote that Clinton did “not recall” the answers to specific questions at least 20 times.

Judicial Watch President Tom Fitton said, “Our lawyers will be reviewing the responses closely. Mrs. Clinton’s refusal to answer many of the questions in a clear and straightforward manner further reflects disdain for the rule of law.”

“Her absolute refusal to answer questions about why she used the system despite warnings about security is notable,” he added in an interview.

Clinton has come under fire for using a private email account and server at her New York home for official emails when she was America's top diplomat.

The email scandal has raised questions about whether Clinton can be trusted to serve as president.

Clinton’s critics, including her Republican rival Donald Trump, have criticized her for endangering government secrets and evading transparency laws.
