The US could still provide $US1 billion ($A1.4 billion) to help replenish Israel's Iron dome missile-defence system, following a move from the leader of the House of Representatives Appropriations Committee a day after the funding was removed from a broader spending bill.
Some Democrats had objected to the provision and said they would vote against the broad spending bill. This threatened its passage because Republicans were lined up against the plan to fund the federal government through December 3 and raise the nation's borrowing limit.
The removal led Republicans to label Democrats as 'anti-Israel', despite a long tradition in the US Congress of strong support from both parties for the Jewish state, to which Washington sends billions of dollars in aid every year.
The United States has already provided more than $US1.6 billion ($A2.2 billion) for Israel to develop and build the Iron Dome system, according to a Congressional Research Service report last year.
Some liberal Democrats have voiced concerns this year about US-Israel policy, citing among other things the many Palestinian casualties as Israel responded to Hamas rocket attacks in May.
Israel said most of the 4350 rockets fired from Gaza during the conflict were blown out of the sky by Iron Dome interceptors.
The bill introduced on Wednesday by Rosa DeLauro provides $US1 billion ($A1.4 billion) to replace missile interceptors used during that conflict.
House Majority Leader Steny Hoyer said on Tuesday evening he would bring the Iron Dome bill to the House floor later this week.
