The State Department says it has no record of Hillary Clinton signing a statement attesting that she had turned over all unclassified documents related to official business when she left her post as secretary of state in 2013.
Department spokeswoman Jen Psaki said Tuesday that neither of Clinton's two immediate predecessors, Colin Powell and Condoleezza Rice, signed such a statement either.
She also said that different bureaus within the department had different rules relating to such statements that had the effect of making their completion optional by some employees. She could not identify the bureaus in which employees had the option to sign or not.
Questions about whether Clinton signed such a document have swirled since the revelation of her use of a personal email account for government-related work.
