You don't have to swear on anything, and you don't even have to swear. It is written into the Constitution that you can affirm, just as you can in court. I believe the Senate is sworn in en masse, so they don't place their hands on anything, but Lieberman would, I assume, use a Torah (unless it would be too unwieldy?).
