Unbelievably ugly ending to Trump press conference.

He storms off after being challenged by two female reporters. One, who is Asian American, had demanded to know why Trump told her she should "ask China" why so many are dying in the United States.

The reporter, @weijia of CBS, held her ground as Trump lashed out.

The full thrust of @weijia 's question was why Trump keeps comparing US stats with other nations.

"Don't ask me, ask China," he said. Weijia followed by asking why that retort was being directed at her 'specifically.'
