The resolution was a harsh bipartisan rebuke to Trump that took the historic step of curtailing a president's war-making powers — a step the president condemned in a statement announcing his veto.
"This resolution is an unnecessary, dangerous attempt to weaken my constitutional authorities, endangering the lives of American citizens and brave service members, both today and in the future," Trump said.
Vetoing the measure is an "effective green light for the war strategy that has created the world's worst humanitarian crisis to continue," said International Rescue Committee president and CEO David Miliband.
"This veto by President Trump is morally wrong and strategically wrongheaded. It sets back the hopes for respite for the Yemeni people, and leaves the US upholding a failed strategy.
