Republican presidential nominee Donald Trump took a gracious tack on Monday, wishing Hillary Clinton a speedy recovery from a bout of pneumonia that has forced the Democratic nominee to cancel a fundraising trip to California this week.

The coughing fit was a week ago, so I assume that was pneumonia also I would think it would have been so, somethings going on. But I hope she gets well, gets back on the trail and well see her at the debate, Trump said in a Monday interview on Fox News .

In a separate interview on CNBC on Monday, Trump called news of Clintons illness quite sad and said he did not revel in it.

I dont take satisfaction. ... I hope she gets well and I hope she gets well soon. But, you know, it was it was quite sad, to be honest with you, he said. I hope she gets well soon. No satisfaction, believe me, whatsoever.

Clinton, 68, abruptly left a 9/11 memorial event in New York City on Sunday morning after feeling ill and overheated, according to her campaign. A video recorded by one witness showed an unsteady Clinton buckle at the knees , requiring the help of aides to get into her vehicle as she was leaving the event. The candidate appeared later looking refreshed as she left her daughters apartment. The campaign released a statement hours later from Clintons doctor, Dr. Lisa Bardack, who announced Clinton had pneumonia and that she was on antibiotics.

Trumps tone on Monday stood in stark contrast to much of the campaign. The 70-year-old real estate mogul has made a habit of questioning Clintons mental and physical stamina and has repeatedly called her a weak candidate.

Neither candidate has released their full medical records, though Clinton has released a more detailed disclosure than Trump. Clinton press secretary Brian Fallon told MSNBC on Monday that the campaign would be releasing additional medical information about Clinton in the next couple of days.

In Trumps interview on Fox News, the businessman acknowledged that health was an issue and announced that he would be releasing the results of a physical he took last week.

This story has been updated with additional information from Hillary Clintons press secretary.
