[Mr. Bird]

Tinfoil activated: if that signature is Chaffee's, he obviously must have thought his name was Lehman.

OK, nothing to see here ...
Pick a better battle.

Lehman signed the Combat Distinguished Service Device, a clarification of the Bronze Star. Zumwalt signed the actual Medal.

My guess is that as he prepared to enter public servce Mr. Kerry reviewed his records and petitioned the Navy to amend his B-Star. Happens ALL the time. This is a losing battle, don't get caught out in the weeds.
