A top campaign aide to Donald Trump blasted Hillary Clinton on Thursday following a new report that she and senior staffers may have skipped federally mandated ethics training when they first began at the State Department.

"Hillary Clinton and her aides reportedly skipped their ethics training. That would make sense since Hillary was planning a criminal enterprise trading government favors for cash," Trump's national policy director, Stephen Miller, said in a statement released by the campaign.

Miller claimed Trump has built his campaign around a promise to restore honor to government and fix the corrupt political system, while his Democratic opponent has been "calculating how much money she can make selling the office of the presidency for profit."

The campaign's latest charge against Clinton comes hours after a report emerged about the difficulties State Department officials have encountered while trying to locate evidence that Clinton and her top aide's completed ethics training as required by law.

The agency has reportedly failed to produce records proving that six senior staffers who worked closely with the former secretary of state — Cheryl Mills, Huma Abedin, Anne Marie Slaughter, Caitlin Klevorick, Jake Sullivan and Kris Bladerston — ever participated in the training.

Mills and Abedin have been closely involved in the controversies dogging Clinton's presidential campaign, and have recently faced new questions about the Clinton Foundation's improper influence over the State Department during the former first lady's four-year tenure at its helm.

Meanwhile, Sullivan has been a senior adviser to Clinton on foreign policy and national security during the course of her bid for the White House.
