Vivek should keep it up: Trump after Ramaswamy's ad against opponent faces backlash

US President Donald Trump backed Republican nominee Vivek Ramaswamy amid backlash for an ad featuring his opponent's estranged mother calling her a liar. "Vivek should keep it up...let everyone listen to...[a] dishonest candidate's [mother]," Trump said. "If my mother...said anything bad about me, the Fake News would play it up...[and] It'd win Awards for Excellence in Advertising," Trump added.
