So much so, Trump, who last week clinched the number of delegates needed to win the Republican party nomination for US president, has been declared “America's Berlusconi”.
The things they say - much of it revolving around women, money, power, (and hair) - are also so similar that it's hard to tell whether the words came from Berlusconi or Trump.
So with the help of Marsha De Salvatore, an American-Italian comedian, we put together a quiz to see if you can decipher who said what.
De Salvatore presented the quiz at a Rome Comedy Club show on Friday night, and needless to say, it was difficult for the audience to tell the difference.
See if you can do any better!
