Elizabeth Warren mourns her oldest brother, who died from coronavirus on Tuesday

On Thursday morning, Senator Elizabeth Warren (D-Mass.) announced that her oldest brother, Donald Reed Herring, had passed away on Tuesday from coronavirus. He was 86.

Herring, who tested positive for the illness several weeks ago, died in Warren's home state of Oklahoma. He was a Vietnam veteran and had served in the United States Air Force for 20 years. 

"I'm grateful to the nurses and other front-line staff who took care of my brother, but it is hard to know that there was no family to hold his hand or to say 'I love you' one more time," said Warren to the Boston Globe.

Herring flew 288 combat missions during his service in Vietnam. After a successful military career, he opened up an auto-detailing business.
