The US Senate has passed a resolution to check Trump's power to wage war

A small number of Republican senators in the US joined forces with Democrats to pass a bill aimed at checking President Trump's power to wage war. The bill requires Trump to end the military operations against Iran or seek congressional authorization before continuing the military actions.

According to reports from Reuters and The New York Times, the US Senate passed the "War Powers Act" on Tuesday (June 23rd) with a vote of 50 in favor and 48 against. This act had already been passed by the House of Representatives in early June.

This is the first time that both houses of Congress have passed such a war powers bill since the United States' "War Powers Resolution" (commonly known as the War Powers Act) was enacted in 1973, requiring the president to withdraw US troops from overseas military operations. This reflects that the unpopular war in Iran has increasingly worried some Republicans.

Although this vote was largely symbolic in nature, it still represented a setback for Trump. Previously, the Republican members of Congress had almost unanimously supported Trump.

A White House official said on the 23rd that the Senate's vote was meaningless because the bill would not be sent to Trump for signature. The White House insists that the "War Powers Act" violates the Constitution and therefore has no legal force.

Legal experts point out that the legal validity of the congressional resolution remains controversial and may ultimately require a court ruling.
