It is in Section 615. The funds are labeled as "humanitarian assistance for Gaza".
There is language in the bill that is supposed to shield the money from going to Hamas so Senators can claim it isn't funding Hamas but it will fund Hamas because all money going in to Gaza funds Hamas and everyone knows it. There is a provision saying monitors have to file a report showing the money being diverted.
... but the Senators will be saved from embarrassment because the Hamas diversion report will be classified so it isn't subject to FOIA requests and won't leak to the press.
