Catherine Herridge, the ex-CBS News correspondent who saw her files seized by the network after her controversial firing in February, is set to break her silence before the House Judiciary Committee, The Post has learned.

The acclaimed investigative journalist, known for her reporting on the Hunter Biden laptop scandal, will testify next week before the powerful panel on the still-murky circumstances surrounding her exit from CBS News, according to a source close to the situation.

The potentially explosive hearing — titled “Fighting for a Free Press: Protecting Journalists and their Sources” — will take place at 9:30 a.m. April 11, the source said.

In addition to Herridge, SAG-AFTRA chief news and broadcast officer Mary Cavallaro will speak about the union’s negotiations with CBS to return Herridge’s confidential materials after she was let go, according to the source.
