London Mayor Sadiq Khan again slammed President Trump.

London Mayor Sadiq Khan slammed President Trump on Saturday, reportedly calling him a "six-foot-three child in the White House." 
According to The Guardian, Khan was addressing a group of teachers at an education event when he said his phone was off, adding, "For those of you that have your phones on, if somebody starts tweeting about me – a 6ft 3 child in the White House – can you let me know?" 
The mayor has had a longstanding public feud with Trump, fueled in part, by accusations the U.S. president helped to boost the hard right including sharing tweets from racists, rolling back women's and LGBTQ rights, and separating families at the border. 
In response, Trump has lashed back at Khan, calling him a "national disgrace who is destroying the city of London." 
And earlier this month, the president called him "a stone cold loser."
