The U.S. House of Representatives voted nearly unanimously on Tuesday to reaffirm the NATO alliance’s guarantee that all members defend each other, weeks after President Donald Trump raised doubts about Washington’s support for the agreement.

The vote was 423-4 in the House, where Trump’s fellow Republicans hold a 48-seat majority, for a resolution “solemnly reaffirming” the U.S. commitment to Article 5 of the North Atlantic Treaty.

It also supports calls for every NATO member to spend at least 2 percent of its gross domestic product on defense by 2024.

During a visit to NATO headquarters in Brussels in May that was part of his first overseas trip, Trump pointedly did not mention U.S. support for that critical portion of the NATO charter, rattling allies. Instead, he used a speech there to demand that member states pay more for the alliance’s defense.
