We can still put these people under oath and find out how they destroyed evidence. Who was 'feeding them - and what they knew they didn't tell.
A pardon keeps you out of jail - NOT out from under any accountability.
Plus this begging to get a 'get out of jail' card tells us what they really think of what they did. It's not a surprise democrats put that idiot Liz Cheney on top as 'the face of the committee'... they knew where it was headed.
Not to mention, the can commit perjury during testimony....which is a new crime in itself.
