Sen. Tim Kaine (D-VA) is seeking to bring an amendment limiting military action against Iran to a vote on the Senate floor.

The amendment, to be attached to the National Defense Authorization Act (NDAA), prohibits the use of military funds to support action against Iran’s government or military, except in the case of self-defense, according to Kaine’s office. While introduced in the Senate Armed Services Committee during consideration of the NDAA, committee members voted down the measure as being outside their jurisdiction.

“He’ll be pushing for that, he’s going to try to bring it up to the floor. But it’s ultimately a leadership decision which amendments get a vote,” an aide in Kaine’s office told JI.

The NDAA is expected to be taken up on the Senate floor this summer. Inquiries to both Senate Majority Leader Mitch McConnell (R-KY) and Senate Minority Leader Chuck Schumer’s (D-NY) office were not answered.
