In his latest column, Good Morning Britain star Piers Morgan, 55, urged Donald Trump, 73, to “shut the f**k up” as he slammed the latter for floating the idea of using disinfectants and sunlight to treat coronavirus patients.Piers titled his column: “President Trump's batsh*t crazy coronavirus 'cure' theories are not just shockingly senseless and stupid - they're going to kill people.”He said of Trump: “The most reckless and dangerous thing President Trump has done is use the most powerful podium on earth to air his batsh*t crazy theories about how to beat the virus.“And last night he stooped to a shameful new low by suggesting people suffering from COVID-19 should be injected with toxic disinfectant.“Yes, you read that right.”UPDATE:.
