Congress was in recess at the time, leaving the building mostly empty.
I’ve read (I don’t have any first hand knowledge of it though) that in sign language dialogues both signers can be signing to each other at the same time (full-duplex) as opposed to each speaker having to wait for the other to stop (half-duplex). Might be another thing to file under “neat features”.
