Democratic presidential nominee Hillary Clinton regularly had her maid print out and handle sensitive national security documents, despite the fact that the servant lacked any such clearance to handle the materials, according to a New York Post report published Sunday.

Since it was published, the report has been pushed by the Trump campaign in a press release and also during the Sunday morning talk shows by GOP nominee Donald Trump's running mate Mike Pence and campaign manager Kellyanne Conway. It states that Clinton regularly had Maria Santos, a Filipino maid who worked at her D.C. residence, print out emails for her, including official documents Clinton received as secretary of state. She also told aides to forward messages to Santos for that purpose.

The report by Hoover Institution media fellow Paul Sperry cites redacted but otherwise unclassified emails released as part of a probe into whether Clinton use of a private email server violated federal law. In a 2011 email from Clinton to her top assistant Huma Abedin, for example, she said: "Pls ask Marina to print for me in am." In some cases the emails contained information that was officially marked as classified at the time, which is a rating below "secret" for government documents.

The report also cites a classified 2012 email regarding the president of Malawi, in which another Clinton aide, Monica Hanley, said to Clinton, "We can ask Marina to print this."

"Yet it appears Clinton was never asked by the FBI in its yearlong investigation to turn over the iMac Santos used to receive the e-mails, or the printer she used to print out the documents, or the printouts themselves," the report stated.

Santos refused to talk to the Post for the article.
