US citizen Leo, who has clashed with Donald Trump over several issues, submits his vote by post in Chicago

Pope Leo has voted in the US midterm elections – the first time a sitting pontiff is known to have cast a ballot in any political election at any time in history.

Leo, who has clashed with the US president, Donald Trump, over several issues, submitted his vote by post in Chicago, where he was born, the Vatican said on Friday. Leo became the first American leader of the Catholic church last year after the death of Pope Francis.
