Former Mexican President compares Trump to Hitler

Former Mexican President Vicente Fox says that US presidential candidate Donald Trump "believes in white supremacy", and he is standing by his comparison of Mr Trump to Adolf Hitler.

Mr Fox has also said that the Republican presidential front runner "lies and lies and lies and uses whatever is convenient for him without any attention to facts".

Mr Trump has proclaimed that he will build a wall across the entire US-Mexico border and insists that Mexico pay for it.

In an interview last week, Mr Fox did not hold back in using profane language, stating, "I'm not going to pay for that f-ing wall" and proceeded to call Mr Trump a "crazy guy".
