Senate Democrats finally crack GOP unity on Trump's Iran war as Murkowski flips

Senate Democrats have tried to splinter off Republicans from their near-unified backing of Operation Epic Fury for months with a campaign of attrition, putting war powers resolution after war powers resolution on the floor ever since fighting began. 

And after two months of trying, they finally got some in the GOP to flip on Trump with Sen. Jeff Merkley's, D-Ore., latest attempt. Still, it wasn't enough to terminate ongoing operations in the Middle East. 

However, Trump, after rejecting the latest proposal from Iran, said on Tuesday that the fragile truce is on "life support."

"I would call it the weakest, right now, after reading that piece of garbage they sent us - I didn't even finish reading it," Trump told reporters. 

"I would say the ceasefire is on massive life support, where the doctor walks in and says, 'Sir, your loved one has approximately a 1% chance of living,'" he said.

Whether Trump's trip overseas and the deadline now in the rearview mirror would have an impact on Wednesday remained an open question heading into the vote.

"People have their own minds about some of these issues, and this is not a new vote, it's one we've had many times before, but you know, we'll see what votes are," Thune said. 

Murkowski warned earlier this month that unless there were signs that a peace deal was nearing completion or further communication from the administration on their objectives, she would bring an AUMF to the floor. 

"I think the president - our view is that he has all the authorities he needs under Article II to execute," Hegseth said.

"But I see almost no circumstance in which Republicans would want to have a vote on that in committee or on the floor," Kaine told Fox News Digital. "They are actively trying to avoid accountability for the war."
