Billions of US Tax Dollars going to Cuba and other foreign countries?

From Mark Tapscott:

Two U.S. senators and a representative worry that billions of tax dollars could be going to Cuba and other foreign countries via criminal schemes designed to defraud Medicare and Medicaid.
The schemes often involve the use of “nominees,” individuals who are paid to be fronts for the actual owners of corporate entities being used in the fraudulent operation. By concealing the identities of true owners, the approach invites its use to funnel tax dollars out of the country.
In a letter made public yesterday to Marilyn Tavenner, acting administrator of the Center for Medicare and Medicaid, senators Orrin Hatch, R-UT, and Tom Coburn, R-OK, were joined by Rep. Peter Roskam, R-IL, said they fear billions of tax dollars are being lost annually as a result.
“Clearly, the program vulnerabilities that facilitate billions of dollars to be stolen from the Medicare program each year also allow for some of that money to be funneled to foreign countries,” the three congressmen said.
“While the fraud itself is unacceptable, the loss of American dollars to foreign countries because of flaws in our system is totally unacceptable. The American people deserve the peace of mind to know that federal officials are doing everything they can to safeguard taxpayers’ dollars and the Medicare program.” . . .
