One of Donald Trump’s most senior African American aides has gone public with criticism of the White House after resigning amid reports of a blazing row at a Christmas party.

Omarosa Manigault, who appeared on The Apprentice, said she saw things while working for the president that made her “very uncomfortable” and “unhappy”.

She did not deny claims she was concerned by Mr Trump’s stance on Charlottesville, where a woman died in clashes with white supremacists, and Roy Moore, the controversial Alabama senate candidate.

Ms Manigault even hinted at producing a tell-all account of her time in the White House, declaring she had “a profound story that I know the world will want to hear”.

African-American voters were credited with the Republicans' shock Alabama election defeat this week, in which Doug Jones, a lawyer who once prosecuted three high profile Ku Klux Klan members, became the first Democrat to win a Senate seat in the state in a generation.
