No , I missed it who was under question? (If it was the Energy sec. I watched about 15 mins. this morning but not much happened.)
At one point Rangle wanted to swear in the wittinesses and Thomas came back with the fact that they as employees of the Federal Government, they effectively already were. So if Rangle wanted that, it would be fine with Thomas as long as the Committee members who were in a similar situation would also have to submit to a reaffirmation oath.
