A group of Senate Democrats voted Tuesday in favor of advancing a resolution sponsored by Sen. Bernie Sanders (I-Vt.) to potentially freeze U.S. military aid to Israel, sending a pointed message to President Biden that the war in Gaza is becoming a major problem for his party.

The Senate voted 72 to 11 to table the matter, but the number of Democrats who supported the measure reflects rising dissatisfaction among progressives over the civilian casualties in Gaza, which are now said to exceed 24,000.
