Donald Trump's sentencing delayed after US Supreme Court ruling ...

Donald Trump was due to be sentenced in his hush-money case next week, but it has been postponed by at least two months so the judge can consider a new request from Trump's lawyers.

Trump's legal team wants the opportunity to argue the conviction should be overturned because of this week's Supreme Court ruling on presidential immunity.

Judge Juan Merchan will rule on the request on September 6, with sentencing pencilled in for September 18.

A New York judge has delayed Donald Trump's sentencing for criminal conduct until September at the earliest, after the former US president asked for a chance to argue he should have been immune from prosecution.

The former president's sentencing, for falsifying business records to disguise hush money paid to porn star Stormy Daniels, had been set for July 11.

But it faces potential complications after the US Supreme Court ruled on Monday, local time, that ex-presidents have some immunity from criminal prosecution in some circumstances.

The postponement delays the sentencing until at least September 18, well after this month's Republican National Convention, where Trump is set formally to accept the party's nomination for president in this year's race.

There was no immediate comment from Trump's campaign or Manhattan prosecutors, who brought the case.

The court ruling on Monday granted broad immunity protections to presidents for "official acts" carried out during their term in office.

It also restricts prosecutors from citing any "official acts" as evidence in trying to prove a president's "unofficial acts" violated the law.

Hours after it was issued, Trump's lawyers requested that New York Judge Juan Merchan set aside the jury's guilty verdict and delay the sentencing to consider how the ruling could affect the hush-money case.

The judge wrote that he would rule on September 6, and the next date in the case would be September 18 "if such is still necessary".

Trump's legal team has argued that Manhattan prosecutors placed "highly prejudicial emphasis on official-acts evidence", including Trump's social media posts and witness testimony about meetings at the White House.

Prosecutors said before the judge's ruling that they believed those arguments were "without merit" but that they would not oppose adjourning the sentencing for two weeks as the judge considered the matter.

In May, Trump was convicted on 34 counts of falsifying business records arising from an attempt to cover up a $US130,000 ($195,000) hush-money payment to Daniels just before the 2016 presidential election.

Daniels claims she had a sexual encounter with Trump in 2006 after meeting him at a celebrity golf tournament. Trump has repeatedly denied that claim, saying at last week's debate with President Joe Biden: "I didn't have sex with a porn star."

Prosecutors said the Daniels payment was part of a broader scheme to buy the silence of people who might have gone public during the campaign with embarrassing stories alleging he had extramarital sex.

Trump's former lawyer Michael Cohen paid Daniels and was later reimbursed by Trump, whose company logged the reimbursements as legal expenses.

Falsifying business records is punishable by up to four years behind bars, though legal experts say the maximum sentence is highly unlikely in Trump's case.

Other potential penalties include probation, a fine or a conditional discharge, which would require Trump to stay out of trouble to avoid additional punishment.

Trump is the first ex-president to be convicted of a crime.
