Donald Trump teases ‘big announcement’ amid speculation about 2024 presidential run

Donald Trump has said he will make a "very big announcement" on 15 November, as speculation continues that he is about to announce a 2024 presidential run.

Confidants spent much of Monday putting it about that the former US president was on the brink of announcing his intention to become a future president at a campaign rally in Dayton, Ohio.

The crowds shuffling into a corner of the local airport, run by a company named after the Wright brothers who invented the first aeroplane in their Dayton bicycle shop, were excited that they might be about to witness history and their man on his way back to the White House.

An announcement would have come as no great surprise to any of them as "Trump 2024" has been in the works for months now. But in the end it didn't come at all.

Still, Trump ratcheted up the expectation a little further with the promise of something big next week from his Florida home.

"Not to detract from tomorrow's very important, even critical, election," he told a crowd that waited hours for this moment. "I'm going to be making a very big announcement on Tuesday, November 15, at Mar-a-Lago in Palm Beach Florida. We want nothing to detract from the importance of tomorrow."

Trump was ostensibly in Ohio to campaign for the Republican candidate for the US Senate, JD Vance, who polls say is struggling to stay ahead of his Democratic rival, Tim Ryan, in a race that could decide control of the Senate. But the vast majority of the former president's 100 minute speech was, as ever, about himself.
