A feud between US President Donald Trump and the father of a UCLA basketball player detained for shoplifting in China has reached a fever pitch, with the President labelling LaVar Ball an "ungrateful fool".
Continuing a volley of insults over social media that has gone on for over a week, Trump took after LaVar Ball, the father of university basketball player LiAngelo Ball, in a series of tweets.
Trump chastised LaVar Ball for failing to credit him with interceding with Chinese officials to get his son LiAngelo and two other UCLA basketball players released after they were detained in connection with a shoplifting incident while in China to play a basketball game.
Tweeting from his Mar a Lago estate in Florida before daybreak, Trump said, "The ungratefulness is something I've never seen before."
