Joe Biden formally announces 2024 White House run

In a three-minute video opening with images of the US Capitol attack, Biden warned that the US remains under threat from the anti-democratic forces unleashed by his predecessor, who he beat in 2020.

The president launched his re-election campaign on the fourth anniversary of his return to politics in 2019, when he declared his third presidential run. Since then, the political landscape has changed.

The US is still grappling with the scars of a pandemic that killed more than 1.1 million and with inflation that has eased from historic highs but remains painful. Americans remain deeply divided, convulsed by the loss of federal abortion rights, near-weekly mass shootings and worsening climate disasters.

Already the oldest president, Biden would be 86 before the end of a second term, nearly a decade older than Ronald Reagan was when he left the White House in 1989. Trump is 76.

The president and his wife, Jill Biden, had made his intentions known. But Biden felt little need to rush after a better-than-expected Democratic performance in the midterm elections tamped down calls for a serious primary challenge.

Biden is dogged by low approval ratings and concerns about his age. Only a quarter of Americans want him to run, according to the Associated Press-NORC Center for Public Affairs Research. Among Democrats, that figure is 50%. Should Biden win the nomination, as expected, most Democrats will support him.

On Tuesday, Biden was due to welcome the president of South Korea. Next month, he will travel to the G7 summit in Japan. His team will begin to formalize a campaign expected to be headquartered in Wilmington, Delaware.

Biden has made clear he plans to run on accomplishments in the first half of his presidency, when Democrats had majorities in Congress.

Biden signed the American Rescue Plan, delivering financial assistance to those hit hard by Covid. He also approved a $1tn infrastructure bill; signed the first major federal gun safety bill in nearly 30 years; pursued initiatives to both treat veterans exposed to toxic burn pits and boost the semiconductor industry; and made Ketanji Brown Jackson the first Black woman on the supreme court.

Perhaps his most significant legislative achievement to date is the Inflation Reduction Act, the most significant US response to the climate crisis.

Biden must negotiate with a divided Congress, Republicans holding the House. Biden plans to use a showdown over raising the federal borrowing limit to draw a contrast with Republican economic priorities, which he argues are aligned with big business and special interests.

In his campaign video, Biden warned that individual freedoms are under attack by far-right Republicans who have trampled reproductive, voting and LGBTQ+ rights.

Trump resisted efforts to retrieve materials he took to his Florida estate. But that is just one of many legal challenges he faces. Earlier this month, Trump pleaded not guilty to 34 criminal charges related to hush money payments to a porn star. He also faces investigations into his efforts to overturn the 2020 election, trial over a rape accusation, and a civil suit over his business affairs.
