But Herridge’s most recent assigment — covering the Hunter Biden probe — put her under a microscope at the left-leaning network, The Post has learned.

It was well understood on Capitol Hill that Herridge was among the first to receive tips about the Hunter Biden investigation but she ran into “internal roadblocks at CBS News,” sources said. ...

Herridge’s departure comes as the journalist faces heat for not complying with US District Judge Christopher Cooper’s order to reveal how she learned about a federal probe into a Chinese American scientist who operated a graduate program in Virginia.

Critics ripped CBS for ousting Herridge when she is fighting for the rights of journalists, with one CBS News insider calling the network’s decision “tone deaf.”
