Former US President Donald Trump chose JD Vance, the rookie senator from Ohio, as his vice presidential pick. Back in 2016, JD Vance emerged as a vocal critic of Donald Trump saying he's "a Never Trump guy" and "I think that Trump's noxious and is leading the white working class to a very dark place".
