President Donald Trump will speak Wednesday with Secretary General Mark Rutte about possibly pulling the U.S. out of the North Atlantic Treaty Organization as fellow members of the 77-year-old military alliance have not backed the U.S. war with Iran—though Trump can’t do it without congressional approval.

Key Facts
- Press Secretary Karoline Leavitt said Trump has considered withdrawing from NATO, the 32-member alliance that acts as a collective military defense for the countries under its banner.
- Trump cannot unilaterally withdraw the U.S. from NATO under a 2023 law that says withdrawal requires a two-thirds Senate approval (right now, including at least 14 Democrats supporting it) or a formal act of Congress.
- That law was co-sponsored by then Sen. Marco Rubio, R-Fla., Trump’s secretary of state, who recently told Fox News that after the war with Iran, “we are going to have to reexamine” the U.S. relationship with NATO.
