The United States Senate late Tuesday blocked a war powers resolution that would cut US military involvement in the conflict in Yemen.
By a vote of 55 to 44, senators voted against a procedural motion that would have advanced a resolution to withdraw US armed forces from a conflict.
The resolution to end US support for the Yemen conflict sought to invoke the 1973 War Powers Resolution, which gives Congress the authority to overrule the president and withdraw military aid within 30 days if it decides a conflict is unauthorized.
Supporters argued against the ongoing US military assistance to Saudi Arabia and other countries in the ongoing conflict with the Houthi group in Yemen, which they said was contributing to one of the worst humanitarian crisis in the world.
The Trump administration and Republican Senate leaders opposed the motion, arguing that the logistical support and mid-air refueling support services the US military is carrying out did not require congressional approval.
They argued that US involvement was needed to counter Iran's malign influence in the region. Ahead of the vote, US Defense Secretary James Mattis traveled to the Capitol to lobby senators to block the resolution.
It comes on the same day as the Crown Prince of Saudi Arabia Prince Mohammed bin Salman al-Saud meeting with President Donald Trump in Washington for bilateral talks on regional security issues and strategic objectives.
