Senate Majority Leader Chuck Schumer (D-NY) and Minority Leader Mitch McConnell (R-KY) are putting on a united front to pass the defense supplemental spending bill.

A bipartisan working group of senators has spent more than a month negotiating a border security deal, which would be added to a defense spending bill that includes aid for Ukraine, Israel, and Taiwan. Negotiators on both sides have acknowledged that the border measure is critical to passing the legislation through both chambers.
