An ousted federal official will be front and center today, testifying before Congress about the coronavirus response, and he's got a bleak warning for the remainder of the year and possibly beyond.

Dr. Rick Bright is giving fair warning that without more action, the year 2020 “will be the darkest winter in modern history.”

Bright, who filed a whistleblower complaint, is testifying before the House Energy and Commerce Committee today.

According to his prepared testimony, Bright says the United States will face “unprecedented illness and fatalities” unless more preparations are made.

"We don't have a test that is widely available, that is fast and that is reliably accurate," says Dr. Sanjay Gupta, CNN Chief Medical Correspondent.

Bright will also say the Trump administration was not properly prepared for the COVID-19 pandemic. President Donald Trump dismisses Bright as someone with a grudge.

"To me, he's a disgruntled guy and I hadn't heard great things about him," says President Trump.

Bright was the head of the biomedical advanced research and development authority, he says he was removed because he wouldn’t promote widespread use of a drug President Trump was touting as a possible treatment for the virus.

"I am not disgruntled, I am frustrated at a lack of leadership, I am frustrated at a lack of urgency to get a headstart on developing life-saving tools for Americans," says Dr. Bright.
