Donald Trump, who has mounted relentless attacks on the integrity of U.S. voting since his 2020 election defeat, on Tuesday launched a bid to regain the presidency in 2024, aiming to pre-empt potential Republican rivals.

Trump, seeking a potential rematch with Democratic President Joe Biden, made his announcement at his Mar-a-Lago estate in Florida a week after midterm elections in which Republicans failed to win as many seats in Congress as they had hoped.

In a speech broadcast live on U.S. television, Trump spoke to hundreds of supporters in a ballroom decorated with several chandeliers and lined with dozens of American flags.
