U.S. Senate Votes To Check Trump’s War Powers

The U. S. Senate has approved a resolution instructing Donald Trump to end the war in Iran or seek congressional authorization to continue it.

Although the resolution does not have the force of law, it marks the most significant bipartisan reprimand yet of the conflict.

From the New York Times:

The 50-to-48 vote — in which four Republicans joined Democrats in favor — marked a striking break by the G.O.P.-led Congress with a president who has faced little resistance from his party on any topic, particularly matters of war and national security.

It came as Republicans in Congress have expressed skepticism and alarm about the cease-fire agreement Mr. Trump struck with the Iranians.

And it underscored a growing impatience among them as the war was approaching its fifth month about continuing to defer to the president, who has never sought approval from Congress for the war, while further negotiations over its end appear precarious and Mr. Trump has threatened more military action.

Four Republicans joined Democrats in approving the measure. Sen. John Fetterman (D-PA) was the lone Democrat to vote against the resolution. The House of Representatives passed the resolution earlier this month.

Today’s vote marks the first time since 1973 that both chambers of Congress have approved a concurrent resolution directing a president to end a military conflict.
