President Joe Biden had several mental lapses and gaffes during the G7 summit in England this weekend. In a press conference on Sunday, June 13, the president had stumbled while speaking about Russia ahead of his June 16 meeting with Russian President Vladimir Putin in Geneva, Switzerland.

According to a The Blaze report, Joe Biden had confused Libya with Syria on two more occasions.

Earlier, First Lady Jill Biden had said that her husband was so well prepared for the conference, saying that he has been studying weeks for the meeting.

The president had also mistakenly said COVID when he meant to say COVAX during the presser. He further noted that COVID is the system whereby they are going to provide funding for states to get access to vaccines.

The White House had issued a statement correcting the blunder. Biden had reportedly made the gaffes on three different occasions during the press conference.

Joe Biden had also interrupted U.K. Prime Minister Boris Johnson when he was introducing other world leaders, saying that the prime minister did not mention South African President Cyril Ramaphosa. But Johnson insisted to Biden that he already introduced the president of South Africa to the G7 meeting.

The G7 Summit

Meanwhile, Joe Biden said that America is "back at the table" after the G7 summit of world leaders in the U.K. The president noted that the conference had been extraordinarily collaborative, according to a BBC News report.

The group of leaders had released a joint communique on Sunday, June 13, stating solidarity and the differences that remain when it comes to addressing a series of global crises.

The group did not reach an agreement on a timeline to eliminate the use of coal for energy generation. Climate activists said that it was a deep disappointment before a global climate conference that would take place this year.

Joe Biden said the leaders' endorsement of a global minimum tax would ensure global equity and proposal to fund infrastructure projects, The New York Times reported.

Johnson said that gathering was an opportunity to show the benefits of democracy. The G7 leaders had also agreed to take action on China's human rights record.

Biden had also tried to distance himself from former President Donald Trump, who said he believed climate change was not a problem.

Biden noted that it is an existential problem facing humanity, and it is being addressed that way. The G7 had also introduced a spending plan to support lower and middle-income countries in response to a similar Chinese plan.

The summit had also called for a transparent, expert-led study including China amid claims that COVID-19 may have leaked from a Wuhan lab. The World Health Organization would organize the initiative.

Joe Biden's Gaffes

In the past, Biden has already made several verbal missteps, including calling his vice president, Kamala Harris, "President Harris" while celebrating the U.S. nearing the administration of 100 million COVID vaccine doses, New York Post reported.

The president had also mixed up his sister and wife during a victory speech in March 2020. Without looking at the two women behind him, Joe Biden grasped his wife's hand and said, "this is my little sister Valerie," Evening Standard reported.
