It's interesting that the federal judge in DC refused to find Trump et al in contempt for ignoring that subpoena. She isn't a Trump supporter like Judge Cannon. She was telling the Justice Department to indict Trump now, instead of playing games to get more evidence. The subpoena was to get a Master of Records to sign a statement (under penalty of perjury) that all stolen records have been returned. But DOJ knows exactly what classified records Trump checked out and which he has not returned. None of Trumps lawyers are willing to sign as Master of Records since Haba got burned by Trump, so they probably thought "Let's get Trump to sign it, and take the fall for perjury."

But the judge thinks the witness box would be the proper place to just ask Trump if all the records have been returned. Then when he says yes, they can introduce their "not returned list" and prove he just committed perjury. Or he pleads the fifth or poor memory, and their list proves he has violated the Espionage Act.

Educating anyone benefits everyone.
