Senate Advances Iran War Powers Resolution With Cassidy’s Support

The Senate advanced an Iran war-powers resolution in a 50-47 vote, with Bill Cassidy voting to move it forward. Left-leaning outlets frame Cassidy’s vote as a post-primary break with Trump and raise questions about its timing. Center outlets mainly explain the resolution, Cassidy’s support, lawmakers’ differing views and the measure’s uncertain prospects. Right-leaning outlets also connect the vote to Cassidy’s primary loss but describe it as a reversal or defection.
