Sources close to IGN are reporting that Senate Majority Leader Bill Frist has nearly succeeded in his effort to amend a Port Securities bill with prohibitive Internet gambling legislation. Frist, R-Tenn., has reportedly added provisions introduced by Rep. Jim Leach, R-Iowa, which target U.S.-based banks, credit card companies and other Internet payment systems, prohibiting them from making payments to online gambling companies. As of this afternoon, signatures are being collected on the bill. The amended Port Securities bill need only receive the signature of the President to be enacted.
