Former Secretary of State Hillary Rodham Clinton says in a sworn statement submitted to a federal judge on Monday that she has turned over all emails reflecting official government business.

The statement, which carries her signature and was signed under penalty of perjury, echoes past public statements that Clinton has made in the last few months regarding her private email account.

In the statement, she declared that she had directed all emails from her personal account “that were or potentially were federal records” be provided to the State Department. She said 55,000 pages of emails were turned over to the State Department last December.

The declaration was made as part of a lawsuit filed by the conservative group Judicial Watch, which had sued for records related to Clinton’s tenure as secretary of state.

Clinton acknowledged use of her private email account in March. She said she used it as a matter of convenience to limit the number of electronic devices she used.

Federal investigators have begun looking into the security of Clintons’ email setup amid concerns from the inspector general for the intelligence community that classified information may have passed through the system. Clinton’s lawyer, David Kendall, has said he and Clinton are “actively cooperating” with the FBI inquiry.

Clinton has said she exchanged about 60,000 emails in her four years in the Obama administration, about half of which were personal and were discarded. She has said she turned over the other half to the State Department.
