MINNEAPOLIS — Minnesota Sen. Amy Klobuchar announced Monday that her husband, John Besser, has tested positive for the coronavirus.

The former Democratic presidential candidate said in a statement that Besser began feeling sick when she was in Minnesota and he was in Washington, D.C., and he immediately quarantined himself. She said he sought a test and chest X-ray after he began coughing up blood, and was checked into a Virginia hospital with “very low oxygen levels which really haven’t improved.”

She said he now has pneumonia and is on oxygen but not a ventilator. Klobuchar said her doctor had advised her not to get a test.

“One of the hardest things about this disease is he’s in the hospital today, he’s been in there for a few days, and I can’t even be by his side,” Klobuchar said during a teleconference to discuss legislation Monday.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.

She said it took five days for Besser to be tested, noting that such delays are a problem facing many.

“We have to fix that immediately in this country,” she said.
