Mr Anderson faced questions from Coalition members about the appropriateness of politically-charged tweets by ABC employees. “Where is the line between what the ABC will stand behind in a program and a journalist’s social media profile?” he asked. Mr Porter is now suing the ABC in the Federal Court for defamation and Mr Anderson told Senate estimates he was limited in what he could say about the reporting. Mr Anderson said the ABC reporting on Mr Porter was impartial, in the public interest and the journalism was of the “highest quality”. Mr Anderson said he was “always worried” about federal funding cuts to the ABC but he didn’t expect reprisals.
