The mystery of "covfefe" deepened on Tuesday morning as US President Donald Trump suggested his now-infamous tweet had a "deep meaning".
In May 2017, Trump - notorious for his tweeting - sent out an early morning message on Twitter saying "Despite the constant negative press covfefe". It stayed online for about six hours.

While many assumed he had mistakenly mucked up the word "coverage", conspiracy theories swirled about whether the apparent accident was actually a secret message.
"I thought it was a hidden message to the Russians," joked former Democratic presidential hopeful Hillary Clinton. But many others seriously believed in that theory. Speculation was fuelled when then-White House press secretary Sean Spicer said: "The President and a small group of people know exactly what he means".
But more than two years later, Trump has again suggested the tweet had a hidden meaning.
Responding to a tweet by media outlet Daily Caller noting that a horse named after Trump's "mistweet" had won a race, the President said: "Great! But how do you know it was a "mistweet?" May be something with deep meaning!"
People went crazy in the comment section, saying their minds had been blown.
"Of course it had another meaning! You sir are too funny. Great in the art of trolling," said one person.
"The president who communicates at a 4th grade level wants us to believe that his tweets have deep meaning," wrote another.
