US Politics Live Updates: Trump loses backing of one of his most vocal supporters

That’s where we’ll wrap up our coverage of US politics and the latest in the peace talks between the US and Iran.

Here’s what happened.

US President Donald Trump called departing British PM Keir Starmer a “lovely man”, but maintained his criticism of some of his policies, including energy and immigration 

Veteran political commentator Tucker Carlson has stated that he won’t support the Republican Party in the lead-up to the November US mid-term elections.

Two more men were also arrested in relation to the alleged plot targeting Donald Trump’s UFC event held at the White House. 

And new poll also found that just 31 per cent of Australians trust the US to “act responsibly”, the lowest recorded level in history. 

The United Nations has confirmed that Monday was the first day since the conflict broke out that peacekeepers in Lebanon’s south did not detect any air strikes.

UN spokesperson Stephane Dujarric said that the “lack of activities” continued into the following morning.

Dujarric said peacekeepers “did not detect any trajectories or observe any interceptions” for the first time since early March.

“We welcome this reduction in hostilities, and we very much hope this trend continues for the sake of people on the ground,” he said.

Durajjic said that UN peacekeepers in Lebanon are still seeing ” extensive [Israeli military] ground activities throughout the mission’s area of operations, including armoured manoeuvres, as well as engineering and logistical activities”.

Fewer Australians feel they can trust the US than in any time in history, as trust in China rises at a cautious level.

Lowy Institute polling found that just 31 per cent of Australians now trust in the US to “act responsibly in the world” - its lowest level in the institute’s history.

That’s a five-point drop from last year, and a shocking 25-point fall from 2024, when president Joe Biden was in the White House.

In 2022, 65 per cent of Australians put their trust in US global responsibility.

By contrast, Australian trust in China, our largest trading partner, is rising - albeit to still-wary levels.

The latest numbers show 28 per cent of Australians trust China to act responsibly in the world.

In 2025, that number from the Lowy Institute was 20 per cent.

Donald Trump says Colombia’s conservative political outsider set to be the Latin American country’s next president has thanked him for his election backing.

Abelardo de la Espriella, nicknamed “The Tiger”, won Colombia’s polarised presidential run-off by a razor-thin margin.

Trump repeatedly referred to him as “El Tigre”and said that he’d said nice things about him and the United States in their phone call.

“You know, when people like me, I like them. It’s very simple,” Trump said.

Here are some more of Trump’s comments about outgoing UK Prime Minister Keir Starmer.

The president earlier repeated his sledge that Starmer was no Winston Churchill given the UK’s lukewarm backing for the US strikes on Iran.

Trump made the comments after a question about US support for NATO, saying the US spent “trillions” of dollars protecting Europe.

“By the way, Starmer wasn’t there, and you know what, the people of the UK did not like it that he wasn’t there,” Trump said.

“Starmer said no. Starmer said worse than no. He said we’ll be there as soon as you win. I said we don’t need you as soon as we win before I went in we called him he said oh wow we’ll be there – this was not Winston Churchill.”

Veteran conservative commentator Tucker Carlson says he’ll no longer back the Republican party in the lead-up to the November US mid-term elections.

“I don’t know what I’m going to do,” Carlson says on the latest edition of the podcast, Can’t Be Censored.

Carlson, who supported Trump during the 2024 presidential election, has split with the Republicans, largely driven by Trump’s decision to attack Iran.

He’s repeatedly claimed the US launched strikes at the behest of Israel, leaving Americans worse off.

“I’ve been a consistent defender for 35 years of the Republican Party, I mean very consistent defender, but there’s no defending this,” he said.

“So no, I’m out. And if I’m out, then I think a lot of other people are out.”

Carlson was quick to add he would not be throwing his support behind the Democratic Party.

Two more people in the United States have been arrested in connection with what authorities say was a planned attack targeting President Donald Trump’s UFC cage-fighting show at the White House.

Federal law enforcement officials disrupted the plan a few days before the June 14 White House event, according to court documents.

William Lee Spartacus Falkner of Washington state, was arrested last Friday and charged with conspiracy to commit murder, according to court documents, reports AP.

Jordan W. Rincker, 28, was arrested in Missouri on Sunday and charged with conspiracy to commit murder.

Five people were initially arrested for allegedly plotting to carry out the attack and destabilise the federal government, the US Justice Department said.

Trump has just commented on social media about protesters comparing algae in Washington’s Reflecting Pool with victims of the Nazis in World War II.

His Truth Social post included photos of demonstrator banners with the words “First they came for the algae”.

It was a spin on German pastor Martin Niemoller’s famous poem about the Holocaust.

Trump called it “another example of a crazy pro-algae (likely paid) protestor.”

The president earlier raged against vandals who damaged the National Reflecting Pool - a landmark he has staked much of his political capital on.

Taking to Truth Social, the president said vandalism would be punished and that fixes are already being made.

Iran will establish a Strait of Hormuz “telephone hotline” with the US and other countries to  “prevent and resolve any misunderstandings”.

Iran’s chief negotiator, Mohammad Bagher Ghalibaf, told state media after the latest talks in Switzerland wrapped up his country and the US agreed on setting it up, CNN reports.

He said it would help resolve “any ambiguity or issue” when ships transit the key waterway.

When asked by a reporter about the purpose of the hotline, Ghalibaf replied: “If Americans have any objection to anything, or if any vessels or ships need clarity on any route or anything … they [can] call.”

He also said Iran “will implement international laws precisely” and act quickly to resolve any problems or misunderstandings.

Trump has been speaking about the US-Iran situation, reiterating that preventing Tehran having a nuclear weapon is his main goal.

The president was asked by journalists if he’s willing to risk a global depression by unleashing more attacks against Iran if it fails to uphold its agreement.

“Well, not the way I’m doing it. It’s not going to cause depression.” he replied.

Trump went on to argue that the threat posed by a nuclear weapon is a greater concern.

“If they don’t abide by - well, nuclear weapon supersedes depression.”

He maintained that military action remains on the table if Iran does not comply with the deal.

“If Iran doesn’t live up to their agreement, or if they’re not behaving, I will do what I have to do.”
