My reading was they can't use testimony or notes from advisors in the executive branch who are helping the President perform an official act.
I.e. anything that would have a chilling effect on the President's ability to direct the executive
Outside of that, e.g. campaign staff, is a different matter. And I believe there's already a distinction between government employees and campaign employees (probably for campaign finance reasons).
