WASHINGTON (CBS) — The health of Hillary Clinton and Donald Trump takes center stage in Campaign 2016 tonight.

CBS 2’s Jamie Yuccas reports, Clinton is taking the day off from the campaign trail after she nearly collapsed during a ceremony for the 15th anniversary of the 9-11 attacks.  But it was something she said before the Sunday event that has Donald Trump upset.

Her campaign initially did not reveal she was diagnosed with pneumonia on Friday, but they now say they will be more forthcoming about her health.

“In the next couple of days, we’re going to be releasing additional medical information about Hillary Clinton,” said Brian Fallon, a Clinton campaign spokesman. “We’ve been in touch with her physician this morning to get those together. We’re going to release that to further put to rest any concerns about what you saw yesterday.”

Clinton tweeted from her Twitter account Monday afternoon, thanking supporters.

Donald Trump says he had a physical last week and promises to release the results soon.

Trump wished Clinton well – and then went on the attack over a comment she made about his supporters this last week.

“You can put half of Trump supporters into what I call “the basket of deplorables,” Clinton said during an LGBT fundraiser.

“She and her wealthy donors all had a good laugh,” Trump said. “You heard them, they were all laughing.”

Trump slammed Clinton as an out-of-touch elitist who can’t relate to the common man.

“Hillary Clinton is an insider, supported by powerful insiders, attacking Americans who have absolutely no political power,” Trump continued.

Trump has made his own controversial comments in the past, and a handful of protesters were outside his new Pennsylvania Avenue hotel in Washington, D.C. Monday morning to remind potential guests.

The Trump campaign released a new ad today highlighting Clinton’s “deplorables” comment. She says she regrets criticizing Trump’s supporters, but maintains his campaign has given a platform to hateful views and voices.

But what’s the recovery time for someone with pneumonia?

“A young otherwise healthy adult will often times feel well in one week,” said Dr. Jennifer Earvolino of Rush University Medical Center Internal Medicine. “But an older individual — someone over the age of 65 — it could take several weeks before they feel back to normal.”

Earvolino adds that anyone who has been diagnosed with pneumonia needs to get adequate rest and take care of themselves.
