Re: 16 - that doesn’t matter. He could have directed EOs and pardons be executed previously.
Much ado about nothing unless Biden himself says “I didn’t authorize that being signed”.
He said something very close to that when Mike Johnson asked him why he suspended LNG shipments to Europe.
Biden's answer was "I didn't do that!" Johnson informed him, "Yes you did".
Mike Johnson said that was when he realized Biden's staff had been signing everything in his name without Biden's knowledge.
