Today in Media Files, the fallout from the ABC's 7.30 story about Seven's sacking of a cadet journalist continues, and tweets are getting longer.

Seven's cadet firing fallout continues. The fallout from the ABC's 7.30 story on Monday about the Seven Network's treatment of a cadet journalist continues. Seven board member Jeff Kennett accused the broadcaster on Twitter of failing to go to the network for comment on the story, which has been branded a "lie" by host Leigh Sales, rejected by reporter Louise Milligan and contradicted by a statement from the network included in the report. Kennett has this morning apologised to Milligan, saying his tweet about having no contact was incorrect. On the program's online posting of last night's follow-up story, 7.30 has included a lengthy statement from Seven that said allegations aired hadn't been put to the network.
