Senate Republicans have voted down an effort to halt President Donald Trump’s war against Iran. It demonstrated early GOP support for a conflict that has rapidly spread across the Middle East with no clear U.S. exit strategy. In Senate debate Wednesday, Democratic Leader Chuck Schumer implored fellow senators to ask themselves if they stand with Americans “exhausted with forever wars” or with a president and defense secretary set to “bumble us headfirst” into another one. Sen. John Barrasso is second in Senate Republican leadership and said Democrats would rather obstruct Trump than “obliterate Iran’s national nuclear program.”
The House is preparing to vote on a war powers resolution that would halt President Donald Trump’s attack on Iran. Thursday's roll call will offer a snapshot of the support or opposition in Congress for the widening conflict that's reordering U.S. priorities at home and abroad. It’s the second vote in as many days. The Senate defeated a similar measure along party lines Wednesday. Lawmakers are confronting the sudden reality of representing the nation in wartime and all that entails — with lives lost, dollars spent and alliances tested by a president’s decision to attack Iran. Republicans largely back the war, while Democrats oppose. But there are splinters in the parties.
