Journalist Matt Taibbi joined HuffPost Live on Friday afternoon to discuss his latest article on JPMorgan Chase and whistle-blower Alayne Fleischmann, his first piece in Rolling Stone since parting ways with First Look Media in October.

Taibbi's reasons for leaving First Look after only eight months -- before ever launching his highly-anticipated digital publication, Racket -- have been the source of much speculation in the media in recent weeks.

Though he declined to go into detail about what exactly soured his relationship with the company and billionaire-founder Pierre Omidyar, he did expound on his general feelings of sadness over the failed project and the messy break up.

"I am sad that it didn't work out," he said to host Alyona Minkovski. "I'm sad for the people who are still working there. As happy as I am to be back working with Rolling Stone, with whom I've always had a great relationship, this was intended to be the launch story for Racket and I'm sad about that."

But when pressed to further comment on the specific reasons behind his departure from First Look Media, Taibbi demurred.
