I appreciate the spirit of Mr. Fergus's suggestion, but I would like to leave it as is and would note for him, and for you, Madam Chair, that the subamendment doesn't relitigate the question of a summons versus an invitation. I think the invitation speaks to the proposed witness's availability.
I think this satisfies the concerns raised by Mr. Fergus and some of his colleagues with respect to the nature of a summons.
