Biden to address US as clock ticks on presidency

WASHINGTON - US President Joe Biden will give what could be his final Oval Office speech Wednesday to explain why he dropped out of November's election and deny that he will spend six months as a lame duck.

With the world's eyes already on a looming clash between Vice President Kamala Harris and Donald Trump, Biden will insist in his address to the nation that he still has work to do despite his historic decision to bow out.

The 81-year-old Democrat said on X he would discuss "what lies ahead, and how I will finish the job for the American people" in the primetime televised event at 8pm.

The speech, expected to last eight to ten minutes, will be Biden's first since stepping aside from the race on Sunday after weeks of pressure following a disastrous debate performance against Trump.

He had promised in his withdrawal announcement -- made while he was isolating with Covid at his Delaware beach home -- that he would give Americans more details on his stunning decision.

It comes just over a week since his last Oval Office address following an assassination attempt against Trump on July 13, but is only the fourth of his presidency overall -- and could well be his last.

With Harris, who has effectively clinched the Democratic presidential nomination, and Trump both back on the campaign trail, Biden will be fighting an uphill battle to show Americans he is not yesterday's man.

Republicans have called for Biden to step down altogether, saying that if he is not fit to stand for reelection then he is not fit to serve as president.

The veteran Democrat insists he still has much to offer, with a particular focus on the economy and on achieving an elusive ceasefire in Israel's war against Hamas in Gaza.
