Joe Biden has been forced to pull out of a campaign speech after contracting COVID.
The US president was due to deliver an address to UnidosUS – the nation’s largest Hispanic civil rights and advocacy organisation – in Las Vegas.
Mr Biden is experiencing mild symptoms, the White House said, including “general malaise” from the infection.
He has returned to his home in Delaware to self-isolate and from where he will “continue to carry out all of his duties fully during that time”, Press secretary Karine Jean-Pierre said.
A post on the president’s X feed said simply: “I’m sick.”

Seconds later he appeared to qualify the first tweet by posting “of Elon Musk and his rich buddies trying to buy this election.”
He added: “And if you agree, pitch in here” adding a link to his fundraiser site.

Asked by the press how he was feeling, the 81-year-old said: “Good. I feel good.”
He then walked cautiously up the stairs to his plane.
An official said Mr Biden presented this afternoon with upper respiratory symptoms, including a runny nose and a cough.
The president is vaccinated and boosted, they added. He has also been given a first dose of Paxlovid, an antiviral medicine that works by stopping the virus that causes COVID-19 from growing and spreading in the body.

Mr Biden was asked if there was anything which would make him rethink his candidacy for a second term in the White House during an interview with Ed Gordon of BET News.

“If I had some medical condition that emerged, if somebody, if doctors came to me and said, ‘you got this problem and that problem’,” the president said.
Concerns around Mr Biden’s health have risen since his poor showing in a TV debate with Mr Trump.
The president has since insisted he is “firmly committed” to staying in the race, despite more calls from people within his own party to step aside, including senior congressman Adam Schiff.
The White House said last week that Mr Biden is not being treated for Parkinson’s disease following reports that a specialist doctor had visited the US president several times in the past year.
