Of course, the second guy could just be an idiot. You should contact him and get his thoughts on the trade, as well as getting other league members thoughts.
I rarely call out the veto, but in this case it's probably appropriate. Veto, and if it passes keep a sharp eye out for similar crap. If it happens again and the rest of league doesn't call-out the commish on it, I'd be tempted to give up the $ and drop out.
