Republican presidential candidate Donald Trump suggested that Hillary Clinton has been sick for a while, pointing to her coughing fit last week as evidence that 'something's going on.'

'I really just don't just know. I hope she gets well soon. I don't know what's going on,' Trump said when asked about it on 'Fox and Friends' Monday morning.

He wished Clinton well after her weekend health scare – and revealed he is preparing to release detailed results of his own physical on Thursday.

The big reveal will come on Dr. Mehmet Oz's TV show, according to a report from the Fox News Channel.

Trump's campaign said last week that he would share his 'health regimen' with the Tv doc, but the planned appearance has gained new significance in the wake of Hillary's collapse on Sunday.

Trump was uncharacteristically silent – including on Twitter – on Sunday, even as Clinton was spirited away from a Sept. 11th ceremony in New York, where was captured on video stumbling on the way to her van before her campaign finally revealed she had been diagnosed with pneumonia.

Then he brought up Clinton's prolonged coughing allergy last week, which Clinton jokingly chalked up to a Trump allergy.

'The coughing fit was a week ago, so I assume that was pnemonia also. I would think it would have been. So something's going on.'

Trump also attended the ceremony in New York, but without incident.

'I just hope she gets well and gets back on the trail and we'll be seeing her at the debate,' he added.

Trump indicated he'll be putting out detailed results about his own health.

'I think it's an issue. In fact, this last week I took a physical,' he said. 'I'll be releasing – when the numbers come in, hopefully they're gonna be good, I think they're gonna be good. But when the numbers come in, I'll be really very, very specific numbers, Trump said.

To date Trump, 70, has only released a short letter from a doctor, who the Clinton campaign has noted is not an internist but a gastroenterologist. The letter stated he would be the 'healthiest individual ever elected to the presidency.'

Clinton will be 69 when she takes office if elected.

Trump also commented on speculation that Democrats might have to replace Clinton with vice president Joe Biden or running mate Senator Tim Kaine if her health problems worsen.

'No I don't think they'll replace her,' Trump said. 'We have to see what's wrong we have to see what's wrong. What ever it is, it is I'm ready – whatever it is.'

Several party leaders and Clinton backers told POLITICO that she needed to offer a fuller accounting of her health.

'There will have to be some kind of accounting for this,' said one former Clinton adviser.

Clinton was already facing calls on Sunday afternoon to release her full medical records.
