WHITE PLAINS, N.Y. — Democratic presidential candidate Hillary Clinton said Monday that she’s feeling better since falling ill at a 9/11 memorial ceremony, but she never lost consciousness and didn’t think her pneumonia diagnosis was significant enough to disclose beforehand.

“I just didn’t think it was going to be that big a deal,” she said of the pneumonia diagnosis she received Friday. She told CNN’s “Anderson Cooper 360” that despite doctor’s orders to rest for five days, she thought she could “just keep going forward and power through it and that didn’t work out so well.”

Clinton abruptly left the ceremony and appeared to stumble while she was waiting for her motorcade. Asked whether she fainted, Clinton replied: “No, I didn’t. I felt dizzy and I did lose my balance for a minute. But I got in, once I could sit down, once I could cool off, once I got some water, I immediately started feeling better.”

Clinton’s evening interview came as her campaign scrambled to head off lasting damage from a difficult weekend. Aides are promising to release more of her medical records following her bout of pneumonia and conceding they were too slow in providing information about her condition.

An outbreak of respiratory illness swept through Hillary Clinton’s campaign in the weeks before she was diagnosed with pneumonia, campaign aides said Monday.

Clinton’s husband, former president Bill Clinton, said in an interview Monday with PBS’ Charlie Rose that Hillary Clinton was “doing fine” after a good night’s sleep.
