Update:

According to Politico, Attkisson’s departure stems from her frustration with CBS’ liberal bias:

More from Politico’s report:

CBS News investigative correspondent Sharyl Attkisson has reached an agreement to resign from CBS News ahead of contract, bringing an end to months of hard-fought negotiations, sources familiar with her departure told POLITICO on Monday.

Attkisson, who has been with CBS News for two decades, had grown frustrated with what she saw as the network’s liberal bias, an outsized influence by the network’s corporate partners and a lack of dedication to investigative reporting, several sources said. She increasingly felt like her work was no longer supported and that it was a struggle to get her packages on television.

At the same time, Attkisson’s own reporting on the Obama administration, which some staffers characterized as agenda-driven, had led network executives to doubt the impartiality of her reporting. She is currently at work on a book — tentatively titled “Stonewalled: One Reporter’s Fight for Truth in Obama’s Washington” — which addresses the challenges of reporting critically on the Obama administration.

It remains to be seen where Attkisson will go next, but one thing’s for sure: She’d be a valuable asset to any media outlet:
