The underage prostitutes in the Dominican Republic are probably the tip of the iceberg; it's no secret that D.R. is a magnet for money laundering and tax evasion coming from the U.S. (and Menendez is also the target of an FBI probe into his dealings with two Ecuadorian bank embezzlers). Even the surgeon that apparently colluded with him in D.R. sounds implausible. My guess is that he's a front for one of Menendez's wheel-greasers (oldest trick in the book in politics: never meet with the money, always with a proxy).

It’s also hard to tell just how seriously Sen. Menendez and other hardline policy supporters take Cuba as a security threat. We’ve criticized Sen. Menendez for feeding fears about the end of the Cuban Adjustment Act, a reckless move that could encourage Cubans to risk their lives sailing across the Florida Straits. But his protests that the Cuban Adjustment Act will end as a result of normalization don’t gel with his claims that Cuba is a terrorist state. As a bipartisan group of Senators wrote over a decade ago about the Bush administration’s Cuba policies:

“The idea of Cuba as a terrorist threat is regularly dispelled by the Administration’s practice of promptly admitting Cubans who arrive illegally on our shores, without the background checks imposed on visa applicants in Havana, as if a true terrorist state would not attempt to infiltrate operatives by all means, including by sea.”

Maybe someone can ask the Senator how he feels about implementing the same immigration policies for state sponsor of terror designees Syria, Iran and Sudan. We can probably guess the answer.
