Donald John Trump was at his worst yet again today.

He took questions from reporters on the White House lawn after staging another round of happy talk about how fabulously the nation is doing as it fights the coronavirus pandemic.

Then came a question from CBS News White House reporter Weijia Jiang, who wanted to know why Trump keeps using the U.S. testing regimen as a global competition when more than 80,000 Americans have died from the viral infection.

“Maybe that’s a question you should ask China,” Trump said. Jiang was born in China but came to the United States at the age of 2. “Don’t ask me. Ask China that question, OK?” Jiang pushed back after Trump labeled her question “nasty.” She said it wasn’t … and she is correct. The question was a legitimate query.

Jiang also wanted to know from Trump why he would direct that response to her, given that she is, um, of Asian descent. You know?

A moment later, Trump called a halt to the press conference and fled the podium to return to the White House.

This is how the “wartime president” chooses to conduct himself. He chooses to attack the press when he should be focused on the “enemy,” which in this instance is that virus that keeps inflicting grievous suffering on the nation he took an oath to protect.

Disgraceful.
