Freelance journalist for Noseweek Paul Kirk has defended his comments labelled racist and praises for apartheid leader PW Botha, saying it is pure satire. This as DA senior member Diane Kohler-Barnard faces a disciplinary inquiry for reposting his comments. The DA's shadow minister of police Kohler Barnard has apologised and says she is ashamed that she shared the post. But the party leader Mmusi Maimane says her comments are indefensible and their social network policy is clear that no member can tweet racist comments.
