One day after adopting a resolution aimed at removing US military forces from the conflict with Iran, the Senate walked back its rebuke of President Donald Trump’s handling of the war, rejecting an attempt to advance a similar war powers measure.

Wednesday’s late-night vote came after Trump expressed frustration with Senate Republicans who voted for an Iran war powers resolution on Tuesday, as well as Republicans who misse d that vote, arguing that Congress had undermined his position at the negotiating table with Iran.

GOP Sens. Rand Paul and Bill Cassidy, who had previously voted to rein in the president’s war powers on Iran, changed their votes this; Paul voted present and Cassidy voted against advancing the resolution. GOP Sens. Susan Collins and Lisa Murkowski once again voted for the resolution, while Democratic Sen. John Fetterman again voted against it. The final tally was 47-50-1.

Earlier Wednesday at a tense Senate GOP lunch with Trump, Cassidy went toe-to-toe with the president on Iran, telling him he would continue voting for war powers measures until Congress and the American people are given more information on the conflict.

“I stood and said, ‘You have not told the American people what’s going on. It was supposed to last four weeks, it’s lasted four months. Our original objectives have not been achieved, and I want to know what’s going on,” Cassidy told reporters after the meeting.
