Senate Majority Leader Mitch McConnell has worked out a deal with Democrats to vote on an amendment stating that the president does not have congressional authorization to go to war with Iran in exchange for moving the FY 2020 National Defense Authorization Act forward. The vote on final passage of the NDAA will occur today, June 27, while the vote on presidential authority (or lack thereof) to wage war in Iran will occur tomorrow, June 28.

Friday’s vote will be held open all day to ensure all senators—including those running for the Democratic nomination for president— are able to return to DC following this week’s debates to vote.

Campaign for Liberty supporters who oppose wasting trillions of dollars and thousands of lives on another no-win, unconstitutional war should contact their senators and tell them to vote for the amendment affirming that the president lacks congressional authority to go to war.
