The United States President Donald Trump vetoed a congressional resolution sought to end US involvement in the war led by the coalition to Support legitimacy in Yemen, the White House said early Wednesday.

"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 wrote to the Senate.

The military support is needed to "protect the safety of the more than 80,000 Americans who reside in certain coalition countries that have been subject to Houthi attacks from Yemen," he said.

The bill passed the House 247-175. Sixteen Republicans voted yes with Democrats and one voted present. In the Senate the vote was 54 to 46, with seven Republicans voting with Democrats.
