they ignore Menéndez's real owner: the Caymans money launderer and vulture fund brigand Paul Singer.
Singer used Menéndez for years in hopes of stringing other Senate Foreign Relations Committee Democrats along in his bid to cheat Argentine bondholders out of a billion dollars - for bonds Singer purchased from resellers for just $48 million (the vulture fund dispute). He has already per$uaded a Wall Street judge, the senile Thomas Greasa, to hold other bondholders' payments hostage until he gets his demands - putting Argentina in the unprecedented position of having to sue in order to be allowed to pay creditors (the bondholders).
The Singer vulture fund in this dispute, NML Capital, has already received billions in TARP funds. It's based out of the Caymans, through which they facilitate billions in additional tax evasion - including the Romneys (and almost certainly Menéndez as well).
Menéndez, however, was thoroughly unsuccessful in influencing fellow Senate Democrats against Argentina - especially after Singer forced Caesar's Entertainment to fold using similar vulture fund tactics (Atlantic City may soon declare bankruptcy as a result, costing taxpayers billions more).
So, too much is being made of this Dr. Melgen. Just wait until word leaks out of any secret Cayman accounts being handled for Menéndez by his real owner, the vulture Singer.
