President Donald Trump vetoed a resolution Tuesday that called for the U.S. to end support for the Saudi-led war in Yemen.
"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 in a statement.
Tuesday's move is the second veto of Trump's presidency.
The legislation was originally introduced in the Senate and co-sponsored by presidential candidate Senator Bernie Sanders, invoking the War Powers resolution, a federal law that gives Congress the power to check the president when committing the U.S. to an armed conflict.
The House passed a similar resolution on Yemen in February, but it was not able to reach the Senate due to a procedural issue.
Saudi Arabia has been leading a coalition against Yemen's Houthi rebels since 2015, when Riyadh and its Sunni-Arab allies launched a massive air campaign aimed at rolling back Houthi gains that began in 2014.
The campaign has devastated Yemen's infrastructure, including its health and sanitation systems, prompting the UN to describe it as one of the worst humanitarian disasters of modern times.
