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 outsize influence by the network’s corporate partners and a lack of dedication to investigative reporting, several sources said. She increasingly felt that her work was no longer supported and that it was a struggle to get her reporting on air.
