Require Congress to authorize military action against Iran

Yea

—

Nay

Sponsor: Sen. Tim Kaine (D-VA)

01 · What this bill does

Plain English.

A war-powers joint resolution that, unlike the seven failed attempts earlier in 2026, narrowly passed the Senate 50-47. Required congressional authorization for any US military action against Iran. Subsequently moved to the House.

02 · Why it matters

The stakes.

First Iran war-powers resolution of 2026 to clear the Senate. The 50 Yea votes are the senators who finally drew a line; the 47 Nay votes are the receipt of who refused.

First successful Senate Iran war-powers vote in the 119th Congress.
Three Republicans crossed party lines to vote Yea; three Democrats crossed to vote Nay.
The narrow margin reflects how close the Senate is to challenging executive war powers — and how much money has been spent to keep it from happening.
House action still pending at time of publication.
