You seem to be confused in that you think this recent development that I posted above is about the Stormy Daniels hush money/election finance fraud case.
This development is about Trump lying to his lawyers about which classified documents he retained.
His lawyer signed an affidavit to the court.
If you lie to your attorney and they lie to the court on your behalf, that's obstruction of justice.
Further, the judge in the case has ruled that the special prosecutor had cleared the threshold for showing that Trump used his attorney, Corcoran, in the commission of a crime, invalidating attorney/client privilege under the crime/fraud exception.
Trump's attorney is being ordered to testify in front of the grand jury.
