This week, the U.S. Senate is set to review a $105 billion national security supplemental request from the Biden administration, which includes aid to Ukraine and Israel, efforts to contain China, and tougher border security in the U.S. Meanwhile, House Republicans are planning to vote on an emergency aid package for Israel that does not include funding for other U.S. allies. Senate Majority Leader Mitch McConnell is advocating for the broader national security spending bill, while the House is pushing for a more targeted approach. The outcome of the Senate hearing and the House vote will be critical in determining the future of the Biden administration's national security spending bill.
