Keith Olbermann has just sued Current TV ... claiming the network violated his contract, torpedoed his show ... and still owes him up to $70 million in unpaid compensation.
In the lawsuit, filed in L.A. and obtained by TMZ, Keith says, "After being enticed to leave MSNBC and come to Current with promise of editorial control, freedom from corporate influence and the professional support to produce a high-caliber political commentary show of the type his viewers have come to expect, Keith Olbermann was disheartened to discover Al Gore, Joel Hyatt and the management of Current are no more than dilettantes portraying entertainment industry executives."
Olbermann claims his "public termination" last week was "the latest in a series of increasingly erratic and unprofessional actions undertaken by Current's senior management."
Keith alleges Current was so dysfunctional and broke after the network's first 8 months on the air, Current "still couldn't manage to, literally, keep the lights on."
Olbermann is suing for breach of contract, sabotage and disparagement.
