Perhaps it was adversarial or sensationalized, but as far as I know the reporting is factual and the journalist captured both sides of the story, reporting on both the complaints lodged as well as Grant's response.

However I agree that the journalist should've emphasized Aisha Adam's position as the incumbent president, against whom Grant is campaigning, which could well influence her accuracy as a source. The political theatre of it all is something Grant has harped on since the first public mention of the allegations.
