Penny Lancaster has shared a health issue she believes Donald Trump could be battling. The US president's health has been subject of speculation in recent months, after was seen falling asleep during White House meetings and spotted with bruising on his hands. On Monday (March 16), concerns were raised after the president emerged with a fresh bruise on his eyebrow. Penny, 55, has now suggested her own diagnosis, revealing it's the only thing she "wouldn't hold against him".

The TV personality shared a clip of Trump's previous discussion with French President Emmanuel Macron, where he claimed that prescription drug prices could drop "up to 800 per cent". The footage then cut to US TV anchor Lawrence O'Donnell, who said: "No, you cannot say that. It is impossible for a price to come down more than 100 per cent.

"When a price comes down 100 per cent, Donald, we're going to say this again. The price becomes zero. There is no price below zero, Donald. Imagine how many times his teachers tried to tell him that.

"But Donald Trump alone in that room is the only person there who doesn't know that. He doesn't know that basic arithmetic. Donald Trump is the only graduate of the University of Pennsylvania who does not know that a price cannot come down more than 100 per cent."

Resharing the post to her own Instagram Story on Tuesday (March 17), Penny added the caption: "Does Trump have Dyscalculia... That's the one thing I wouldn't hold against him."

Dyscalculia is a lifelong neurodevelopmental learning disorder that affects a person's ability to acquire arithmetical skills.

The 79-year-old has been repeatedly spotted with bruises since his return to the White House last year.

In an interview with the Wall Street Journal (WSJ), Trump blamed the heavy bruising on a high dose of aspirin he takes on the recommendation of doctors.

"Bruising can be just simply a one-off thing when you have some trauma, you bump into something," Dr. Jonathan Reiner, a professor at George Washington University's School of Medicine and Health Sciences, told CNN. "Aspirin will make you more prone to bleeding."
