I believe President’s can pardon up to their last full day in office. I don’t think President Trump would leave them hanging.
I think too many of us forget something important about Trump. These people have attacked his family and pledged to attack his family long after he is out of office. Look at the AG for New York! It is outlandish.
Trump is not dumb and he knows better than anyone that if he does not clean this up his family will be attacked by lawfare for the rest of their lives.
Didn’t Bill Clinton issue some pardons the morning of his last day in office?
