Hillary Clinton-Am feeling much better

Mrs Clinton was reportedly concerned that news of the illness would be exploited by her opponents.

She was diagnosed on Friday and advised to rest, but continued campaigning.

Her team was forced to go public with the diagnosis on Sunday when she left a 9/11 memorial early, appearing weak.

Speaking to CNN late on Monday, Mrs Clinton said she was feeling "so much better".

She also told the broadcaster that she had not disclosed her pneumonia diagnosis, saying: "I just didn't think it was going to be that big a deal."

The US presidential candidate said she had ignored a doctor's "wise" advice to rest for five days. She said she hoped to be back on the trail in "the next couple of days".

The Democratic nominee acknowledged she had lost her balance during Sunday morning's health scare, but said she did not faint.

"I felt dizzy and I did lose my balance for a minute, but once I got in (the van), once I could sit down, once I could cool off, once I had some water, I immediately started feeling better," she said.
