One of President Donald Trump’s aides and Director of Communications for the White House Office of Public Liaison, Omarosa Newman, has quit her job, The Guardian reports.

Reports gathered said that the former star of Trump’s TV show ‘The Apprentice,’ worked as the director of African-American outreach on Trump’s 2016 presidential campaign.

She’s to leave the administration in January 2018.

According to White House press secretary, Sarah Sanders, Newman’s resignation is effective 20 January, one year since Trump’s inauguration.

However, a source familiar with Newman’s departure had stated that her refusal to defend the Trump’s administration had long been an issue.

She had been reportedly unwilling to talk about Trump’s civil rights record in the wake of his visit to the opening of a new museum in Mississippi on Saturday, December 9; nor was she willing to defend the president’s support for Roy Moore in Alabama – a candidate who claimed America was great during the era of slavery.

It was learnt that her refusal to be a public advocate for the White House as its most prominent African-American woman culminated on the evening of Tuesday, December 12 in a meeting with Chief of Staff John Kelly and several lawyers in the White House Situation Room which ended with her departure from the administration.

The US Secret Service deactivated her pass, and escorted her off the White House complex.

Trump expressed his appreciation for her service and wished her success.
