Donald Trump and Mike Bloomberg, two billionaires with additional gigs in politics, exchanged demeaning taunts on Sunday.

Trump, the President of the United States, mocked the former New York City mayor Mike Bloomberg’s height. He called him “mini Mike” in a tweet, and suggested that he is demanding “boxes or a lift” to stand on during the next debate.

The comment was in line with comments he made to Sean Hannity in an interview that will air prior to the Super Bowl. A clip was previewed on Fox News.

Hannity asked Trump what was the first thing that popped in his head upon hearing Bloomberg’s name. He responded “very little. I just think of little.”

While one could suggest that Trump's response only meant that Bloomberg, with whom he rubbed elbows with for years in New York society, takes up no real estate in his mind, he continued to say that “he wants a box to stand on” then condescendingly added, “it’s okay, there’s nothing wrong, you can be short.”

Bloomberg, according to The Guardian, is 5ft 8in. The average American man, according to Healthline, is 5ft 9in.

Bloomberg, however, declined to “go high” after hearing Trump's remark and through his national press secretary Julie Wood, volleyed back an on-the-record retort about the President and “his fake hair, his obesity, and his spray-on tan.”
