However, the press conference raised further questions about Mr Biden’s mental agility, after he confused Mexico with Egypt in response to a reporter’s query about the current situation in the Middle East.

Referring to the Rafah crossing, between Egypt and Gaza, he said: “As you know, initially the President of Mexico, Sisi, did not want to open up the gate to allow humanitarian material to get in.”

Abdel Fattah el-Sisi is the president of Egypt, while Mexico does not share a land border with Gaza.

“I’m of the view, as you know, that the conduct of the response in Gaza, in the Gaza Strip, has been over the top,” he said.

He said he was “pleased” that the Department of Justice had decided not to pursue him in the courts, but did not address the fact that one reason for the decision was that a jury would acquit him because they would think he was a “well-meaning, elderly man with a poor memory”.

The president began shouting at reporters as they asked him about the report’s findings.

At one point, responding to a question about a perception among some voters that he is no longer fit to serve as president, he replied: “That is your judgement. That is your judgement! That is not the judgement of the press.”

As he was questioned on the findings of the report, which claimed that classified material had been wrongly stored at Mr Biden’s home, he responded: “I did not share classified information! I did not.”

As reporters spoke over him, he shouted back: “Let me answer your question!”

He added that the reason he believed he should remain in office was “because I’m the most qualified person in this country to be president of the United States and finish the job I started.”

The report and press conference come after a series of public gaffes from Mr Biden, in which he claimed to have spoken recently with two long-dead world leaders.

At campaign events in New York this week, he told audiences that he had spoken with Helmut Kohl and Francois Mitterand at a G7 summit in Cornwall in 2021.

Mr Kohl and Mr Mitterand died in 2017 and 1996, respectively, and their countries of Germany and France were represented at the summit by Angela Merkel and Emmanuel Macron.
