Mark Halperin lost his job as an MSNBC contributor when former colleagues and subordinates accused him of groping and unwanted sexual advances during his tenure as an ABC News political reporter.

He is now trying to rehab his career and it is not going well.

The Daily Beast reports that Halperin was very unhappy when MSNBC brass nixed his attempt to repair his career through a possible collaboration with the stars of Morning Joe. So he picked up the phone and called network chief Phil Griffin.

Multiple sources tell The Daily Beast that the conversation earlier this year became acrimonious, with Halperin dishing up vague threats against his former boss.

MSNBC declined to comment on the episode. But MSNBC insiders said Griffin was furious about the conversation and wouldn’t likely take Halperin’s calls in the future.

The hostile exchange was a sign of Halperin’s frustration that his dream of returning to the punditry business—almost two years after numerous women came forward with stories of sexual misconduct—has been thwarted at each turn.

Not only has Halperin’s career revival been curbed by his own ex-employer, it’s been poorly received by the public at large.

A number of Democratic analysts who spoke to Halperin on the record for his upcoming book expressed regret for participating in the project following outrage from critics and the women who accused him of misconduct.
