A top Democrat on the Senate Foreign Relations Committee, Sen. Jeanne Shaheen, has placed a hold on a $2.8 billion weapons sale to Israel, The Hill reported on Friday.

The proposed weapons package includes 40,000 one-ton bombs. The Biden administration had previously withheld similar munitions due to concerns over their use in Gaza and the resulting civilian casualties.

As the Senate Foreign Relations Committee’s top Democrat, Shaheen can place a hold on major arms sales while the State Department addresses lawmakers’ concerns. Semafor first reported that she imposed the hold in July.
