Rudy says: Trump will not answer questions about obstruction, in person or in writing
Obviously. No lawyer would let him testify on that subject. Every possible scenario is bad.
If he testifies truthfully, he’s sunk on obstruction.
If he testifies falsely, he’s sunk on perjury.
If he takes the Fifth, he’s safe legally, but totally sunk politically, since he’s essentially admitting that he has to be quiet to avoid incriminating himself.
The only feasible strategy is to argue that a sitting President can’t be compelled to testify, thus tying the matter up in the courts for a long time and eventually handing it over to a presumably friendly Supreme Court.
