According to this piece out in tomorrow’s Post, one of the player’s in the Curt Weldon investigation seems to be “Bogoljub Karic, a wealthy Serbian businessman who had been barred from visiting or trading with the United States because of his close ties to former Yugoslav leader Slobodan Milosevic.” Apparently Bogoljub hired Weldon’s daughter to get him off the war criminal friends black list.

Here’s some background on him from a 2002 post. And here’s the dossier we pulled for one of the operator’s that had the Karic account before Weldon’s daughter picked it up. It can revealing if you’re not familiar with how the foreign lobbying biz works.
