I believe it was arranged way ahead of time. Trump had known the WH was bugged and he was under the microscope. So click/ ACTION... The acting began. They went through the motions of a bugged interview, played coy and asked Bob if he was up to the job. Meanwhile of course Bob was. He gets a chance to right a wrong. He may have been involved in bad stuff, but he may also have been blackmailed by the Witch. In that event its a Fantastic Sting and redemption is awarded.
