Donald Trump - he's an American citizen. He was officially elected as the president of America some years back. Fine bloke! Always brought a smile on people's faces. He used to call himself the best of the best, some people considered that narcissist.
I think the author is saying that this Andrew Lee bloke, is trying his best of the best to be like Trump.
