Donald Trump stormed out of a press conference after he told an Asian-American journalist to "ask China" when she questioned him over coronavirus testing.
CBS reporter Weijia Jiang, who was raised in China until she was two, asked the US president "why are you saying to me?" before he implied her previous question was "nasty".
The President then appeared to invite another journalist to ask a question while Ms Jiang was still speaking, before back peddling and then storming off the stage.
Ms Jiang had asked the president why his administration continued to boast about conducting the most Covid-19 tests in the world.
