“The Supreme Court has made clear that, subject to the exception for impeachment, the president’s power to grant pardons is “unlimited,” with virtually no oversight or limiting role for Congress.
The president can issue a pardon at any point after a crime is committed and before, during or after criminal proceedings have taken place. The president cannot, however, pardon someone for future crimes. A pardon covers both the offender’s conviction for the crime and the sentence for that crime.”

If I understand correctly, then Hunter can still be charged for any other crime not listed in the pardon. Recalling back to that backstage voice recording of Hunter (suspected) saying he worked out a deal with the prosecution. I wonder how this will tie in? Will Hunter be called to testify against his own family? Would he?
no
Since a pardon relieves him of 5th Amendment protection (no protection needed), his refusal to testify would be contempt of Congress and he could be thrown in jail for as long as he liked.
