Congress has approved legislation that would prevent any president from withdrawing the United States from NATO without approval from the Senate or an Act of Congress.

The measure, spearheaded by Sens. Tim Kaine (D-Va.) and Marco Rubio (R-Fla.), was included in the annual National Defense Authorization Act, which passed out of the House on Thursday and is expected to be signed by President Biden. The provision underscores Congress’s commitment to the NATO alliance that was a target of former President Trump’s ire during his term in office. The alliance has taken on revitalized importance under Biden, especially since Russia’s full-scale invasion of Ukraine in February 2022.
