The House passed a bipartisan measure Thursday that would block Iran from accessing the $6 billion transferred by the U.S. in a prisoner swap, a step Republicans pushed in response to the nation’s alleged role in the deadly attacks last month by Hamas on Israel.

The measure — titled the No Funds for Iranian Terrorism Act — passed 307-119 as Republicans sought to hold the Biden administration accountable for what they call its complicity in funding Iranian-backed terrorism in the Middle East.

“With such instability in the region, the last thing we need to do is to give access to $6 billion to be diverted to more Iranian-sponsored terrorism,” Representative Michael McCaul, the Republican chair of the House Foreign Affairs Committee, said during a debate.

Administration officials have rebuffed this criticism, noting that none of the funds has been made available to Iran and insisting that when it is, it can be used only for humanitarian needs.

Republican critics like McCaul say that despite the money being restricted to aid, it is fungible and could free up other funds for Tehran to provide support to Hamas.
