Cassidy Flips, Senate War Bill Advances05/20 06:11

   WASHINGTON (AP) -- The Senate advanced legislation Tuesday that seeks to 
force President Donald Trump to withdraw from the Iran war, as a growing number 
of Republicans defied the president's direction on a conflict that has spanned 
well over two months.

   Since Trump ordered the attack on Iran at the end of February, Democrats 
have forced repeated votes on war powers resolutions that would require him 
either to gain congressional approval or withdraw U.S. troops. Republicans had 
been able to muster the votes to reject those proposals, but Louisiana Sen. 
Bill Cassidy -- fresh off a primary election loss in which Trump endorsed his 
opponent -- switched sides.

   The 50-47 vote tally showed that a small but growing number of Republicans 
are willing to challenge Trump on the Iran war, even though the effort may not 
advance much further. Three Republicans were absent Tuesday and their votes 
would be enough to defeat the measure, if they maintain their stance on the war.

   Still, the vote showed how Republicans are increasingly uneasy with a 
conflict that shows no signs of ending, is stuck in a fragile ceasefire and is 
causing rising gas prices in the U.S.

   "Republicans are starting to crack, and momentum is building to check him," 
Senate Democratic leader Chuck Schumer said in a statement after the vote. "We 
are not letting up."

   Republican Sens. Rand Paul of Kentucky, Susan Collins of Maine and Lisa 
Murkowski of Alaska had all previously voted for similar war powers resolutions 
and did so again Tuesday. Cassidy supported the legislation for the first time, 
while Sen. John Fetterman of Pennsylvania was again the only Democrat to vote 
against it.

   After his primary election loss last week, Cassidy returned to Washington 
defiant. He said he was proud of his work to uphold the Constitution and would 
carefully consider how he would vote on several priorities of the Trump 
administration going forward.

   Trump's grip on the Senate Republican Conference is potentially slipping 
after Cassidy's primary loss, as well as the president's decision Tuesday to 
endorse Republican Sen. John Cornyn's primary opponent.

   "While I support the administration's efforts to dismantle Iran's nuclear 
program, the White House and Pentagon have left Congress in the dark on 
Operation Epic Fury," Cassidy said on social media.

   "Until the administration provides clarity, no congressional authorization 
or extension can be justified."

   House will also vote on war powers

   Across the Capitol, the House is expected to vote on a similar war powers 
resolution Wednesday, and Democrats are bullish about their chances of passing 
it. Another war powers resolution barely failed in the House last week, the 
vote ending in a tie.

   Even if Congress eventually passes legislation to compel Trump to withdraw 
from the conflict, it's not clear that he would comply. To circumvent 
requirements of the War Powers Resolution of 1973, the White House has claimed 
that it has technically ceased "hostilities" with Iran because there is a 
ceasefire.

   Trump this week said he ordered preparations for an attack on Iran on 
Tuesday, only to call it off to give allies in the Gulf more time to work out 
an agreement with Iran.

   "Peace negotiations are stuck and so day after day after day grocery prices 
climb, gas prices climb," Democratic Sen. Chris Murphy of Connecticut said in a 
floor speech.

   Lawmakers want more information on Iran war

   On Capitol Hill, patience is clearly running out for a war that Trump 
launched without congressional approval.

   Republican Sen. Mike Rounds of South Dakota said he is supportive of Trump's 
decision to go to war, but that more Republicans are growing concerned about a 
long-term plan. The administration may have to go into more detail about that, 
Rounds said.

   The War Powers Resolution of 1973 "does provide an avenue for that 
discussion and debate to occur," Rounds said.

   He said he believes it's not the right time to do that, and he would rather 
"stand strong with the president" at this point. "But I think a number of our 
members maybe just feel like it's time to have the debate."

   Earlier this year, Republican senators voted to advance a war powers 
resolution on the conflict with Venezuela and compelled the Trump 
administration to make its case to Congress for the military campaign.

   A handful of GOP senators forced a final vote on legislation to withdraw 
from the conflict. Two of the Republicans -- Sens. Todd Young of Indiana and 
Josh Hawley of Missouri -- ultimately flipped after Secretary of State Marco 
Rubio agreed to a public hearing about the administration's Venezuela strategy.
