"Officials repeatedly testified to Congress that Iranian access to the U.S. financial system was not on the table or part of any deal," says the majority report of the Senate Permanent Subcommittee on Investigations.
Despite those claims, the Treasury Department, at the direction of the State Department, "granted a specific license that authorized a conversion of Iranian assets worth billions of U.S. dollars using the U.S. financial system," the report says.
Even after the license was issued, U.S. government officials continued to maintain in congressional testimony that Iran would not gain access to the U.S. system, according to the report.
