Does Mark Harmon want CBS to back him up against Pauley Perrette’s claims?

“NCIS” star Mark Harmon is reportedly threatening to sue if CBS can’t “rein in” Pauley Perrette.

Perrette has made allegations that Harmon physically assaulted her.

Harmon, meanwhile, is reportedly threatening to sue Perrette if CBS can’t “control her,” according to a Radar source.

Perrette exited “NCIS” in 2018 after playing Abby Sciuto since 2003.

Perrette is set to star in a new CBS sitcom, “Broke,” this fall.
