Doctor Sanjay Gupta has claimed US President Donald Trump has heart disease, despite Dr Ronny Jackson claiming he passed his physical examination with flying colours.
Dr Jackson performed a series of tests on the 71-year-old president on Tuesday as part of his first medical exam in office.
After Dr Jackson claimed Donald Trump's "overall health is excellent", Dr Sanjay has called into question the numbers showing calcium in the blood vessels that have steadily increased since 2009.

"Steadily, up until just this past week when he had it performed again, those numbers have gone up," he said on CNN.
"When they get to a certain range... that means he has heart disease."
After speaking with Dr Jackson, he claims he admitted he had heart disease.
"It was interesting when I spoke to Dr. Jackson. At first he said he passed all the tests with flying colours," Dr Gupta said.
"When I asked him specifically about that test, he did then concede that, in fact, the president does have heart disease."
Dr Jackson has already increased Mr Trump's cholesterol-lowering medication and recommended a low-carbohydrate and low fat-diet.
Social media sceptics
Social media users have responded to the claim and other parts of the assessment - mainly Trump's height recorded at 6'3 - with mixed opinions.
One of the most popular 'girther movement' tweets was a photo of Mr Trump's driver's license claiming he was 6'2' back in 2012.
The term girther is a play on the well-established "birther" movement that appeared when right-wing activists opposed President Obama.
The birther movement questioned the birthplace of former president and his eligibility to hold office. The movement was put to bed when Mr Obama released his birth certificate in 2011.
