US President Joe Biden has “thrown a grenade" at Kamala Harris’ plans for the 2024 presidential election, Sky News host James Morrow says. His remarks come after Mr Biden recently labelled Donald Trump's supporters "garbage". “Not for the first time, Joe Biden has gone and thrown a grenade into the whole narrative and said something that now has got – I think for now the third day straight – the Harris campaign on the run,” Mr Morrow said.
