On the one hand, his established relationships with world leaders could instantly make the New York senator a welcome face in embassies around the world.
On the other, his complicated global business interests could present future conflicts of interest that result in unneeded headaches for the incoming commander-in-chief.
"These are issues that I'm sure are being discussed, and they will have to be worked out, and it's legitimate to ask these questions," said James Carville, a former aide to the Clintons and CNN contributor.
