The top House Democrat on the Appropriations Committee introduced stand-alone legislation on Wednesday that would provide $1 billion for Israel’s Iron Dome air defense system — just one day after House Democrats nixed the provision from a government spending bill amid pushback from progressives.

“The United States’ commitment to the security of our friend and ally Israel is ironclad. Replenishing interceptors used to protect Israel from attacks is our legal and moral responsibility,” House Appropriations Committee Chairwoman Rosa DeLauro said in a statement.
