All US immigrant visa applications have been paused by the Trump administration as the state department moves to tighten restrictions and limit access to applicants who they deem could end up relying on US assistance, a state department official confirmed Tuesday.

The agency launched the initiative at all embassies and consulates in early August, according to the official and visa appointments had to be adjusted to accommodate “in-depth training”, according to the official. The state department has been working on updated guidance and training since early this year, “to ensure all consular officers are fully equipped to evaluate every visa applicant comprehensively and consistently”, they added.

Financial Times reports that applicants with interviews already scheduled were sent emails that their appointments had been canceled and that they would be informed of a new date and time.

Agency officials claim this will ensure visa applicants will not end up relying on US public benefits. But it’s part of a slate of strategies the Trump administration has employed to crack down on both lawful and undocumented immigration and create a more selective process for who can gain entry into the system.

This week the Trump administration also announced plans to revoke visas from asylum seekers who initially entered the country for tourism or business. Up to 200,000 people currently seeking asylum could be impacted, marking what would end up being the largest mass pulling of visas in the history of the US. The action is being taken in coordination with the Department of Homeland Security.

The US aircraft carrier USS Abraham Lincoln will make a stop in Thailand after its deployment in the Middle East, Thai officials said.

The Lincoln was supporting the US war against Iran, and its deployment included a record-setting uninterrupted time at sea of more than 250 days, AP reported.

Concerns have grown about the Lincoln’s lengthy deployment following reports of deteriorating mental health among the crew and shortages of supplies including food and hygiene products.

Thai defense ministry spokesperson Surasant Kongsiri said that the Lincoln will stop in Thailand next week for rest and recovery before returning to its US base.

“The stop in Thailand is a chance for the crew to go ashore and relax,” he told reporters at a news conference in Bangkok.

Republican senator Dan S Sullivan will be joined on the November ballot in Alaska by a challenger with a nearly identical name from the same party, election officials confirmed on Tuesday, adding a twist to what is expected to be one of the most hotly contested races of the midterms.

The Republican senator is running for a third term against Democrat Mary Peltola, a former US House representative whom polls show is neck-and-neck with him in a state that hasn’t sent a Democrat to the Senate since 2008.

Alaska holds nonpartisan primaries in which the top four vote-getters advance to the general election. The Associated Press reported that with 85% of the ballots counted, Dan J Sullivan, a retired school teacher and US Forest Service employee running as a Republican, would appear on the ballot alongside incumbent Dan S Sullivan and Peltola, with a fourth candidate yet to be announced.

The other Sullivan entered the race earlier this year, with the incumbent senator condemning him as a “sham” candidate who is running at the behest of Democrats to confuse his supporters and split their votes.

In June, Alaska election officials disqualified the other Sullivan from the election, but the state supreme court ordered him restored. The two were listed next to each other among the 16 candidates on primary ballots, but the senator had “registered Republican” and “incumbent” next to his name, while his similarly named challenger was unadorned.

It’s unclear how much of a threat the other Sullivan may pose to the senator’s chances of winning re-election. His 2.5% of the vote is much less than the more than 48% received by Peltola and almost 43% senator Sullivan won in last week’s primary.

One of the oldest abortion rights groups in the US is endorsing Troy Jackson, the Democratic nominee in Maine’s critical US Senate race, according to details first shared with the Guardian.

Reproductive Freedom for All is supporting Jackson, the former state senate president, in challenging Susan Collins – the five‑term Republican incumbent who has been dogged on the campaign trail for her role in overturning abortion access in the US.

Collins voted in 2018 to confirm conservative justice Brett Kavanaugh to the supreme court. In 2022, Kavanaugh joined the majority opinion overturning Roe v Wade, a landmark abortion rights protection. In the aftermath, more than a dozen states enacted near‑total abortion bans. This year’s midterm elections mark the first time Collins is on the ballot since the decision.

“Flipping the Maine Senate race is a critical path to winning a Senate majority, and we do not restore a federal right to abortion without flipping the Senate majority,” said Mini Timmaraju, the group’s president.

Timmaraju will join Jackson on Wednesday in Brunswick for the launch of the campaign’s Women for Troy coalition.

Hello and welcome to the US politics live blog.

Senator Darline Graham has won the Republican nomination to replace her late brother, Lindsey, on South Carolina’s general election ballot.

Her success marks another win for president Donald Trump after he threw his support behind the political novice.

Graham defeated US representative Ralph Norman in Tuesday’s special Republican primary runoff, two weeks after they were the top two finishers in a 10-way primary.

With nearly all of the ballots counted, Graham had received 52.4% of the vote, according to the Associated Press, ahead of Norman’s 47.6%.

Lindsey Graham, a US senator for more than two decades, won the party’s primary in June, but died the next month. Days later, Darline Graham, was appointed to serve out the remainder of her brother’s Senate term.

“The critics say I shouldn’t run for the Senate,” she told a rally audience Friday. “They say I’m not a politician. You know what I say? Guilty as charged.”

Graham will face the Democratic nominee Annie Andrews, a Charleston-area pediatrician, in November. Andrews faces steep historical odds; the last Democrat to win a statewide race in South Carolina was state superintendent Jim Rex in 2006.

Trump recommended the appointment of Darline Graham, a career civil servant who was head of South Carolina’s Commission for the Blind, then encouraged her to run for a full term – upending a Republican scramble to select a new Senate nominee.

“What I really want you to do is pretend – please – that I’m on the ballot,” Trump said at a rally in Myrtle Beach on Friday. “Just come and vote.” Trump’s Maga Inc Super Pac spent more than $800,000 in support of Graham during the campaign.
