The Senate voted 50-48 in favor of the war powers resolution, which passed the House of Representatives early this month, reflecting growing concern even among some of Trump's Republicans about the unpopular conflict that began on February 28.NDTV reported.
It was the first time both chambers of Congress had passed a resolution directing a president to remove US armed forces from hostilities, as spelled out in the War Powers Resolution of 1973, more commonly known as the War Powers Act.
While likely to remain largely symbolic, the votes were a clear setback for Trump, who until recently enjoyed nearly full support from Republican members of Congress. Trump's Republicans hold slim majorities in both the Senate and House.
