US President Joe Biden’s latest blunder-filled speech at a Nato summit made him sound like he was speaking pidgin English, a top linguist says.

In a woeful set of speeches in Washington DC on Thursday Biden mistakenly introduced Volodymyr Zelensky as “President Putin” before mixing up Kamala Harris with Donald Trump.

The blunders marked the latest in a string of errors Biden has been ridiculed for as even his most senior Democratic colleagues call for him to quit.

Now even former President Barack Obama is thought to be manoeuvring behind the scenes to get him out of the race.

With major Democratic donors reportedly calling for Biden to be replaced or they’ll freeze $90million worth of pledges to the party.

The largest pro-Biden super PAC, Future Forward, has said their funding is on hold for the foreseeable future, claim two sources who the New York Times say have been briefed on the conversations.

Bumbling Biden’s verbal skills have rapidly “unravelled” in recent weeks with almost every time he talks proving to be more worrying than the last, says Columbia University linguist John McWhorter.

Biden, 81, made an offensive Zelensky mix-up in front of Nato leaders and reporters that quickly elicited gasps from around the room.

One way to understand what is happening is to think of it as unravelling

Biden quickly fixed the mistake as he greeted Ukraine‘s leader – the man who has tried to stop Putin decimating his country for over two years – onto the stage.

“Going to beat President Putin, President Zelensky. I am so focused on beating Putin,” Biden went on to correct.

Speaking at a separate press conference later in the evening, Biden then confused his Vice President Harris with his political foe Trump.

McWhorter, also a New York Times columnist, described the elderly president’s speech as a total calamity.

He wrote in his most recent column that the garbled nature of Biden’s words seemed like a mix-up of two or more languages. 

The top linguist said: “It is alarming to see someone who is asking to be elected president of the United States – someone who already serves as president of the United States – communicate in such an ineffective manner.

“But what is actually going on there, linguistically? One way to understand what is happening is to think of it as unravelling.”

McWhorter says he is amazed at how far Biden’s use of language has “strayed from the complexities and subtleties he once controlled effortlessly” in interviews from his previous election trail.

The manner in which he spoke in the debates against rival Trump back in 2020 is why many picked Biden over the controversial Republican.

But he is now using “chunks” rather than forming proper sentences, says McWhorter.

He pointed to a recent interview with ABC where a slurring Biden exclaimed “large crowds, overwhelming response, no slipping”, in broken English.

Another bizarre turn of phrase used in the damming interview saw him say: “I’ll feel as long as I gave it my all and I did the goodest job as I know I can do, that’s what this is about.”

The sentence was quickly picked out and blasted online with even ABC later adjusting it in its transcript to read “I did good as job.”

The confusing sentence was described as being pidgin language by the linguist who said it was concerning to see such a “rapid decline of complex sentence structure”.

McWhorter continued: “‘Pidgins do a basic job but aren’t designed for detail, grace or suasion. Increasingly, Biden’s speech submits to an alarmingly similar judgement.”

It comes as Biden finally conceded that he would quit the 2024 presidential race for the White House if “everyone says we want someone else”.

While speaking at a news conference yesterday, Biden was asked if he would give his blessing to Democratic colleagues if they choose to shift their support to another candidate.

But the president swore: “It’s not going to happen.”

It comes as he also mistakenly called himself a “black woman” during a radio interview this week.

The president also appeared to forget the name of Sir Keir Starmer after he became the new UK Prime Minister.

Sir Keir hit back at claims the US President was “senile” after holding an hour-long bilateral meeting in the White House.

When asked by the BBC whether Biden was senile after an increasing number of people are implying that he is, the PM slapped it down.

He said: “No, we had a really good bilateral yesterday, we were billed for 45 minutes, we went on for the best part of an hour, we went through a huge number of issues at pace.

“He was actually on really good form.”
