Several CBS News reporters were caught up in layoffs at Paramount Global that claimed 800 jobs, including one who is embroiled in a high-stakes First Amendment fight — and another who has reportedly weathered HR probes over his workplace behavior, The Post has learned.

Catherine Herridge — an award-winning senior correspondent whose First Amendment case is being closely watched by journalists nationwide — was among the hundreds of employees at CBS parent Paramount who got pink slips on Tuesday, sources told The Post.

Insiders said Herridge had clashed with CBS News president Ingrid Ciprian-Matthews — a sharp-elbowed executive who was investigated in 2021 over favoritism and discriminatory hiring and management practices, as revealed by The Post.

Sources said CBS News’ Washington bureau, where Herridge covered national security and intelligence, was hit particularly hard.
