Joe Biden's wife feared he was having a stroke during his disastrous presidential debate with Donald Trump in 2024.

Speaking to CBS, Jill Biden spoke of her fear while watching his performance.

"I was frightened, because I had never ever seen Joe like that before or since. Never," she said.

"As I watched it, I thought, 'Oh, my God, he's having a stroke.' And it scared me to death."

The former First Lady made the remarks in an interview that is set to air in full later this week.

During the debate, Joe Biden repeatedly lost his train of thought, gave confusing or nonsensical answers and was unusually belligerent with Trump when it came to his golfing prowess.

It triggered calls for Biden to drop out of the race.

But in the immediate aftermath of the debate, Mrs Biden was publicly supportive.

"You did such a great job, you answered every question," she said at an event with her husband afterwards.

The oldest president in history at the time, Biden was already facing questions about his coherence and vitality.

The unprecedented withdrawal from a re-election campaign came after he had secured the nomination after a series of largely uncontested primaries.

"It was a mistake for the president to stay in the race as long as he did," Democratic Senator Chris Murphy said today.

"We would've been better off as a party had he gotten out much sooner."

Former Obama administration staffer Tommy Vietor thought likewise.

"I think this is how most voters felt while watching that debate, and why it was obvious that Biden had to drop out of the race," he said.

"The impression left by Biden's performance was unfixable, and pretending otherwise was insulting to voters."

Vice President Kamala Harris, who was rushed into the nomination without a primary process, has blamed her election loss on her shorter-than-usual campaign.

She managed to regain the trolley and pushed it back to the store.

The nursery later took to social media to explain what happened and appeal for thieves to stop.

"Please don't let me chase you while I'm nine months pregnant," the owner said.

"And, oh, please don't steal hundreds of dollars' worth of plants from us."

Police say they have not received any reports from the incident.

A man has been charged with murder after allegedly killing a man and assaulting two others south-west of Bundaberg in a series of alleged violent attacks.

The rampage took place over about eight minutes in the small town of Childers, leaving an elderly man dead after he was allegedly brutally bashed with a metal pole.

This allegedly happened after a 36-year-old man, driving a Subaru Liberty, deliberately crashed into a Mitsubishi Pajero.

When the Pajero driver got out of his car after the collision, it is alleged that the offender reversed into him, before punching the other man multiple times in the face.

After this, the 36-year-old drove onto Whietbridge Road in North Isis, where he confronted a 78-year-old man, allegedly punching him in the head before hitting him with a metal pole.

The North Isis man suffered critical injuries and died at the scene.

The Subaru driver then allegedly drove to Crescent Street in Childers, where he allegedly assaulted a 66-year-old man.

He will appear at Gladstone Magistrates Court via video link today.
