US President Donald Trump said Monday he had received an MRI scan during a recent hospital visit, providing an explanation for the first time for why he underwent a second medical exam in a year.

The Republican billionaire — who turns 80 in June — has been accused of a lack of transparency over his health, and his surprise trip to Walter Reed medical center on the outskirts of Washington earlier in October fueled further speculation about his physical condition.

“I did. I got an MRI. It was perfect,” Trump told reporters aboard Air Force One Monday.

“I gave you the full results. We had an MRI, and the machine, you know, the whole thing, and it was perfect,” he added.
