As secretary of state, Hillary Clinton routinely had the maid at her Washington D.C. residence access and print information and documents sensitive to the U.S. government, including at least one classified document, according to a report from the New York Post.

According to the Post, Clinton would receive sensitive information from her top aides at the State Department and in turn ask them to forward the messages, and any attached documents, to her maid, Marina Santos, where they would then be printed out.

However, Santos, according to the Post, does not have a security clearance.

Among other things, Clinton requested Santos print out drafts of her speeches, confidential memos and “call sheets” — background information and talking points prepared for the secretary of state in advance of a phone call with a foreign head of state. “Pls ask Marina to print for me in am,” Clinton e-mailed top aide Huma Abedin regarding a redacted 2011 message marked sensitive but unclassified. In a classified 2012 e-mail dealing with the new president of Malawi, another Clinton aide, Monica Hanley, advised Clinton, “We can ask Marina to print this.” “Revisions to the Iran points” was the subject line of a classified April 2012 e-mail to Clinton from Hanley. In it, the text reads, “Marina is trying to print for you.” Both classified e-mails were marked “confidential,” the tier below “secret” or “top secret.”

According to the report, Huma Abedin, Clinton's right-hand-woman, also told the FBI that Santos had access to the SCIF — which is a highly secured room where diplomatic can set up — in Clinton's D.C. residence.

From within the highly secured room, Santos would retrieve classified documents for Clinton that came through the secured fax line.

Just how sensitive were the papers Santos presumably handled? The FBI noted Clinton periodically received the Presidential Daily Brief — a top-secret document prepared by the CIA and other US intelligence agencies — via the secure fax.

However, despite the FBI knowing about Santos' access to Clinton's classified information, the Post reports that the FBI never asked Santos in their investigation into Clinton's use of a private email server to turn over the computer she used to print out the documents or the documents themselves.

In fact, the FBI never even interviewed Santos as a key witness in their investigation, according to the Post.

Still, Santos could be the person that brings Clinton down because, according to the Post, Santos may know where the missing computer and flash drive that contain a backup of Clinton's email server is located.
