Last week I wrote a piece for Just Security regarding the State Department’s refusal to produce certain officials for depositions requested by several House committees (relating, of course, to the Ukraine affair). Among other things, I addressed the question of whether Congress is required to allow government counsel to attend depositions of the current or former officials of their department or agency. OLC (surprise!) says the answer is yes. In my view, the correct answer is no.
Anyway, I thought it would be helpful to collect the materials in one place. Here is the link to the piece. And here are the relevant House rules and regulations.
