The interesting thing for all his thugs with pardons, is that he can't pardon them for future crimes. If a federal grand jury subpoenas them, the FBI will enforce those. In front of the grand jury, they can either refuse to testify and rot in jail for contempt for as long as any grand jury is in session that wants their testimony, or they can testify about Trump's crimes. If they tell the truth, Trump goes down. If they tell lies, they go down for perjury.

Trump made a fundamental mistake: Never pardon any of your fellow conspirators, because now they can't claim the 5th Amendment to refuse to testify.
