WASHINGTON • US President-elect Donald Trump received plenty of attention - but not the kind he was looking for - after he called out China for its seizure of an unmanned US naval probe on Twitter.
"China steals United States Navy research drone in international waters - rips it out of water and takes it to China in unpresidented (sic) act," he wrote on his favourite platform on Saturday.
"Unpresidented" quickly became a top trending topic on Twitter in the United States, as online wags savaged the incoming president for the unfortunate misspelling.
"TrumpSpellCheck - Unpresidentedly effective," tweeted Harry Potter author J.K. Rowling.
"Dear world, most Americans really wish we could be #unpresidented," another user wrote.
Even dictionary Merriam-Webster weighed in.
"The #WordOfTheDay is... not 'unpresidented'. We don't enter that word. That's a new one," it tweeted.
Mr Trump deleted his tweet after about an hour, replacing it with one correctly using the word "unprecedented".
While many mocked the deeply divisive political novice, famous for his verbal tics and gaffes, supporters jumped to Mr Trump's defence and said critics were focusing on a typo while ignoring the bigger problem.
