Donald Trump welcomed the Senate's reversal of the vote on the Iran War Powers Resolution, calling it a warning to Tehran. Reports say Republican senators Rand Paul and Bill Cassidy switched their positions, changing the tally from 50-48 in favor to 50-47 against, preventing the measure that would limit the president's authority to launch military action against Iran. Trump said the outcome would make Iran take notice and thanked the senators who opposed the resolution. The bill, aimed at restricting unilateral military strikes on Iran without congressional approval, has been a contentious issue in Washington in recent weeks.
