Molly Michael is the John Dean of G. Gordon Liddys, as a pattern emerges.
The sources said Michael also told federal investigators that last year she grew increasingly concerned with how Trump handled recurring requests from the National Archives for the return of all government documents being kept in boxes at Mar-a-Lago -- and she felt that Trump's claims about it at the time would be easy to disprove, according to the sources.
Sources said that after Trump heard the FBI wanted to interview Michael last year, Trump allegedly told her, "You don't know anything about the boxes."
It's unclear exactly what he meant by that.
Trump pleaded not guilty in June to 37 criminal counts related to his handling of classified materials, after prosecutors said he repeatedly refused to return hundreds of documents containing classified information ranging from U.S. nuclear secrets to the nation's defense capabilities, and took steps to thwart the government's efforts to get the documents back. Trump has denied all charges and denounced the probe as a political witch hunt.
As ABC News previously reported, Michael is believed to be the person identified in special counsel Jack Smith's indictment as "Trump Employee 2," described in the indictment as someone who handled many of Trump's White House-era boxes at Mar-a-Lago and who provided Trump with photos of those boxes that were then included in the indictment.
Michael's statements to investigators, described to ABC News by sources, shed further light on the breadth of evidence that Smith has amassed to support his case against Trump.
