Democratic Sens. Sherrod Brown (Ohio), Joe Manchin (W.Va.), Jon Tester (Mont.), Bob Casey (Pa.), Jacky Rosen (Nev.), and Tammy Baldwin (Wis.) are speaking out against the deal.
Democratic opposition to the deal is rising amid the escalating conflict between Hamas and Israel.
Iran has denied any involvement in the Hamas attacks on Israel despite its longstsanding support for the Palestinian militant group.
Brown, the chairman of the Senate Banking Committee, said the panel “will examine the financing behind Hamas’s attacks, including whether cryptocurrency was involved.”
The committee will also explore “what additional economic tools we need to anyone who supports terrorism, including Iran, from supporting Hamas and other terrorist groups.”
The White House has maintained that the Iranians have not yet accessed the $6 billion in question. The money currently sits in a restricted Qatari bank account and may not be accessed for anything other than humanitarian purposes.
The Biden administration has said it does not have direct evidence of Iran helping Hamas in its attacks on Israel, but U.S. officials have described Tehran as broadly complicit in the militant group’s actions.
