The Senate voted on Friday evening to start work on the defense supplemental spending package, teeing up a marathon of amendment votes in the coming days.

The upper chamber voted 64-19 on a motion to proceed to the $95 billion package, which includes aid to Israel, Ukraine, and Taiwan. Senators are facing a partial cancellation of their two-week recess as leadership works to pass the bill, which has been in the works for months and faces a difficult path forward in the House.
