US President Joe Biden said he is “proud” to be the “first black woman to serve with a black president” during a radio interview with Philadelphia’s WURD radio station as the country celebrated Independence Day on Thursday. 

The 81-year-old presidential candidate mistakenly identified himself as Vice President Kamala Harris and confused his current political position with being former President Barack Obama's vice president, following a series of gaffes that have been recurring since last week's presidential debate.

These public instances from Biden are becoming more frequent.

On Wednesday, Biden gave an interview on a nationwide Black talk show, The Earl Ingram Show, where he gave incoherent answers to Ingram's questions.

“You need someone, someone who is going to make sure that – the Supreme Court just issued a decision, by the way, that threatens the American principle that we have no kings in America. There’s no one above the law," Biden said, referring to Trump's recent immunity when asked about the importance of voting.

Although Biden has insisted that he is able to beat Trump in the upcoming elections and perform his duties, his address to Democratic governors contradicted his claims.

According to the New York Times, he told the Democratic officials that he needs more sleep and fewer work hours, adding that no activities be scheduled for past 8 pm.

House Democrats call on Biden to drop out of the race

Some elected Democrats who support President Joe Biden raised new concerns on Tuesday, about his campaign for re-election in 2024, with one suggesting he should consider stepping down. This marks a change after many had previously defended him following his uncertain performance in last week's debate.

According to Democrats and political strategists, the decision whether Biden proceeds with his 2024 presidential bid, following his less-than-stellar debate against Republican candidate Donald Trump, largely rests with him.

Some donors are urging Biden to consider stepping down, and other Democrats are openly expressing concerns that he may not be capable of defeating Trump in November.

After the first debate, a Reuters/Ipsos poll revealed that one-third of Democrats believe Biden should halt his re-election campaign. US Representative Lloyd Doggett became the initial congressional Democrat to advocate for Biden's withdrawal from the presidential race on Tuesday. In an interview for NBC News, he expressed his wish for other Democratic legislators to join him in this stance.

Biden's challenges have extended beyond his immediate advisors, with some US officials accusing him of being complicit in the ongoing Israeli genocide in Gaza. This reflects growing criticism within political circles regarding US foreign policy and its implications for the ongoing war on Gaza.
