Donald Trump said mysterious red marks recently spotted on his hand could have been the result of "AI".

DailyMail.com captured the former president leaving Trump Tower with the marks on his hands two weeks ago.

At an event in Washington on Wednesday Trump was asked if he had seen the photographs, and said he had not.

He was then asked what had been wrong with his hand, and raised his right one, before a reporter clarified that they were referring to his left.

Asked what had happened to the hand the former president said: 'Nothing. Maybe it was AI.'

At the time the red marks appeared Trump was on his way to court to watch E. Jean Carroll testify in a defamation case in New York.

That resulted in an $83 million judgment against him.

Representatives later said the red marks had resulted from paper cuts, and Trump had subsequently smeared blood across his hand.

The marks led to a flurry of speculation on social media.

Theories included that it was red ink from top secret documents.

Others speculated that, owing to the ex-president's love of fast food, that it was ketchup.

Hours after the pictures were taken Trump reappeared showing no signs of the mysterious red marks, and there were further no signs of an injury.
