Stein is German for stone.
Stone has many biblical references. Some of them not so good.
Or we could say Jack and Jill went up the hill to fetch a pail of water — Jack fell down and broke his crown and Jill came tumbling after... okay being kind of facetious here, but I wonder if one of the principles in this effort is named Jack?
Hmmm, maybe John (Jack is nickname for John) Podesta. Only Jack/John I can think of..
