Congress taking first votes on Iran war as debate rages about US goals

WASHINGTON (AP) — The U.S. Senate is headed towards a vote Wednesday on President Donald Trump's decision to embark on a war against Iran, an extraordinary test in Congress for a conflict that has rapidly spread across the Middle East with no clear U.S. exit strategy.

The legislation, known as a war powers resolution, gives lawmakers an opportunity to demand congressional approval before any further attacks are carried out. The Senate resolution and a similar bill being voted on in the House later this week face unlikely paths through the Republican-controlled Congress and would almost certainly be vetoed by Trump even if they were to pass.

Nonetheless, the votes marked a weighty moment for lawmakers. Their decisions on the five-day-old war — which Trump entered without congressional approval — could determine the fates of U.S. military members, countless other lives and the future of the region.

“Wars without clear objectives do not remain small. They get bigger, bloodier, longer and more expensive,” said Senate Democratic leader Chuck Schumer at a news conference Tuesday. “This is not a necessary war. It’s a war of choice.”

After launching a surprise attack against Iran on Saturday, Trump has scrambled to win support for a conflict that Americans of all political persuasions were already wary of entering. Trump administration officials have been a frequent presence on Capitol Hill this week as they try to reassure lawmakers that they have the situation under control.

“We are not going to put American troops in harm’s way,” Secretary of State Marco Rubio told reporters in a raucous news conference at the Capitol Tuesday.

But six U.S. military members were killed over the weekend in a drone strike in Kuwait.

Trump has also not ruled out deploying U.S. ground troops. He has said he is hoping to end the bombing campaign within a few weeks, but his goals for the war have shifted from regime change to stopping Iran from developing nuclear capabilities to crippling its navy and missile programs.

“I think they are achieving great success with what they've done so far,” Senate Majority Leader John Thune said Tuesday, adding that what happens next in the country will be “largely up to the Iranian people.”

Almost all Republican senators were readying to vote Wednesday against the war powers resolution to halt military action, but a number still expressed hesitation at the idea of deploying troops on the ground in Iran.

“I don’t think the American people want to see troops on the ground,” said Sen. Bill Cassidy, R-La., as he exited a classified briefing Tuesday. He added that Trump administration officials “left open that possibility,” but it wasn't an option they were emphasizing.

The votes in Congress this week represented potentially consequential markers of just where lawmakers stand on the war as they look ahead to midterm elections and the consequences of the conflict.

“Nobody gets to hide and give the president an easy pass or an end-run around the Constitution,” said Sen. Tim Kaine, the Virginia Democrat leading the war powers resolution. “Everybody's got to declare whether they're for this war or against it.”

Republican leaders have successfully, though narrowly, defeated a series of war powers resolutions pertaining to several other conflicts that Trump has entered or threatened to enter. This one, however, is different.

Unlike Trump's military campaigns against alleged drug boats or even Venezuelan leader Nicolás Maduro, the attack on Iran represents an open-ended conflict that is already ricocheting across the region. For Republicans who are used to operating in a political party dominated by Trump and his promises of keeping the U.S. out of foreign entanglements, the moment represented a bit of whiplash.

“War is ugly, it always has been ugly, but we're taking out a regime that has been trying to attack us for quite some time,” said Sen. Markwayne Mullin, an Oklahoma Republican.

Meanwhile, Sen. Lindsey Graham, a South Carolina Republican who has long pushed Trump to engage overseas, argued that the widening conflict represented an opportunity for Arab and European countries to join in the fight against Iran and the militant groups it supports.

“I don’t mind people being on record as to whether or not they think this is a good idea,” he told reporters, but also argued that too much power over the military was ceded to Congress in the War Powers Act, which mandates that presidents must withdraw troops from a conflict within 90 days if there is no congressional authorization.

On the other side of the Capitol, House leaders were also readying for an intense debate over the war followed by a vote Thursday.

"I do believe we have the votes to defeat it, I certainly hope we do,” House Speaker Mike Johnson said after an all-member briefing on Tuesday night.

Meanwhile, House Democratic leader Hakeem Jeffries said he expected a strong showing from Democrats in favor of the war powers resolution.

As lawmakers emerged from a closed-door briefing Tuesday night, Rep. Gregory Meeks, the top Democrat on the House Foreign Affairs Committee, implored the Trump administration to “come to Congress” and speak directly to the American people about the rationale for the war.

His voice filled with emotion as he said, "Our young men and women's lives are on the line."

A rule change for primary voting in two Texas counties created mass confusion Tuesday that eventually led to a state Supreme Court ruling, threats of more legal action and the potential that an untold number of voters could find themselves disenfranchised.

The chaos had the most direct potential impact on the Democratic primary for U.S. Senate. The county with the greatest number of affected voters includes Dallas and is the home base for Rep. Jasmine Crockett, an outspoken critic of President Donald Trump who was in a tight race with state lawmaker James Talarico.

Crockett told supporters Tuesday night that the race can’t be settled without the results from Dallas County.

“I can tell you, people were disenfranchised,” she said.

The unfolding chaos — first over the new voting rules, and then over the court decisions and whether late ballots would be counted — stemmed from a change by local Republicans that is unique to Texas' primary system, but also hinted at the type of uncertainty that many have feared lies ahead for November's midterm elections.

The problems in Texas began when voters in two counties — Dallas and Williamson, north of Austin — were turned away at polling locations and directed to different precincts after a recent change in how the primary is conducted.

In Dallas County, a judge ordered polls to remain open for two hours past the scheduled 7 p.m. closing time, citing “voter confusion so severe” that it caused the website of the county election office to crash. The judge was acting on a petition filed by the local Democratic Party in a heavily left-leaning county. Democrats in Williamson said they succeeded in getting two precincts to stay open late.

Later in the evening, the Texas Supreme Court acted on requests by the Texas attorney general's office and stayed both decisions. Its brief orders said ballots cast by voters in both counties who were not in line by the 7 p.m. scheduled close of polls should be separated. The number of ballots affected could not immediately be determined.

Renea Hicks, a longtime Texas appellate lawyer, said the Supreme Court’s action was preliminary and does not say whether the ballots will eventually be counted. That’s something the court will have to sort out in the coming days, he said.

“That doesn’t mean ‘throw them away.’ It doesn’t meant they won’t count,” he said. “We don’t know what it means.”

In both counties, voters had been allowed to cast their ballot anywhere in their county for years. But for this primary, the local Republican parties opted against countywide voting. State law says both major parties have to agree to the countywide system for it to be in effect.

That meant that on Tuesday all voters could cast ballots only at their assigned precinct.

Both Crockett and Talarico denounced the effect of the change on voters, with Crockett saying it was an “effort to suppress the vote.” Talarico's campaign aid it was “deeply concerned” about the reports of voters showing up at polling locations and being sent elsewhere.

Adding to the confusion was the fact that voting locations also might be specific to someone’s party affiliation, said Nic Solorzano, a spokesperson for the Dallas County Elections Department.

“We’re seeing a lot of people that are going to their vote centers that they usually go to ... and not realizing they can’t do that anymore. They have to go to their precinct-based location,” he said.

The extensions in Dallas applied only to Democratic voting precincts. Voting also was extended for an hour in El Paso County after problems with voter check-in systems earlier in the day.

Texas was one of three states kicking off the 2026 midterm elections Tuesday, along with North Carolina and Arkansas. Voting otherwise went fairly smoothly, except for a problem with electronic poll books in one rural North Carolina county that prompted the state elections board to delay the release of statewide results by an hour.

Tomas Sanchez, a student at Dallas College, was among those who showed up at a voting location on campus to cast his ballot in Texas' Democratic primary. But he was under a “mistaken impression” and told that he needed to vote at his assigned precinct, a location about 6 miles (about 10 kilometers) away and closer to his neighborhood.

“This is something that we were really concerned about, honestly,” Solorzano said. He added that after nearly seven years of voters being able to cast their ballots anywhere in the county, “then we kind of had to retool our entire operation to go back to precinct-based voting for Election Day.”

The county elections department has been putting up signs, running ads and sending text messages and mailers to make people aware of the change. On Election Day former poll workers were stationed outside voting locations with tablets to help people find the correct place to cast their ballot.

While Solorzano said his department was not keeping track of how many people were been turned away, local Democrats said the number was significant.

Brenda Allen, executive director of the Dallas Democratic Party, said her offices were swamped by hundreds of calls from voters of both parties trying to find their precincts. She noted that congressional districts in the county also were remapped in Texas’ mid-decade redistricting and that new precinct lines were only finalized in December, leaving little time to inform voters.

“Lots of reports of people being turned away, hundreds of people unable to vote. Both parties are affected by this,” Allen said. “It’s not great.”

In Williamson County, the local Democratic Party headquarters was slammed by calls, executive director Madison Dickinson said.

“We’re having significant problems with the precinct-level voting,” she said, adding that, like in Dallas, even Republicans were confused by the change and were calling the Democratic Party for help.

Republicans were less vocal about the changes online, although the Dallas County Republican Party posted a link showing voters where to find their assigned polling places. The Williamson County Republican Party did not respond to a request for comment.
