Former US President Donald H. Trump's lawyer, Michael Cohen, has revealed racist remarks, some against blacks in the United States, during his campaign in 2016.

According to The Guardian newspaper, Cohen told Vanity Fair magazine that Trump repeatedly used racist language before being elected to take over the White House.

"I told Trump when he was a candidate that most of his voters were white," Cohen said in a statement on Friday. "Trump responded by saying that it was because black people were stupid enough to elect him.

Confession with sins
Cohen adds that Trump had previously asked him to remind him of "the name of a single country ruled by a black man and not overwhelmed by problems," and he insisted on the question.

The White House declined to comment on Trump's racist comments, the magazine said.

Cohen's allegations come after the memoirs of the former White House assistant to Trump Umarosa Manigolt Newman of African descent.

Newman says Trump was a racist, and that he used the word "Negre" - meaning Negro or Black - repeatedly, while she was a contestant in the program "Abrantes" (Reality TV).

The Daily Telegraph reported that Cohen admitted in August that he was guilty of eight charges at the federal level, including tax evasion, bank fraud and campaign financing.

He points out that while acknowledging his sins, Trump said he had ordered him to arrange a payment before the 2016 election to buy the silence of actress Sturmie Daniels and former porn model Karen McDougall, who claimed Trump had sex with them.

The report concludes that the verdicts against Cohen will be issued on December 12, in various cases and charges.
