It's called "criminal intent" and "obstruction of justice". The Washington Post indicated that there is surveillance video corroborating the witness testimony.
Washington – An individual who worked at former President Donald Trump's Mar-a-Lago resort has told investigators that the former president directed the individual to move boxes of sensitive documents – including those that might contain classified markings – to a different location as the federal investigation into Trump's handling of certain records was already underway, according to a person familiar with the matter.
The employee is now a cooperating witness in the Justice Department's probe – which escalated after the execution of a search warrant on Trump's Florida residence in August – and has appeared before a federal grand jury in Washington, D.C., CBS News has confirmed.
The news of a cooperating witness in the documents investigation with firsthand knowledge of the boxes being transferred was first reported by The Washington Post.
