Without context it's hard to say.
I would recommend you not to address the problem yourself, but follow the chain of command and bring it to the attention of your OM in regards to harassment/toxic work environment (see Harassment-Free Workplace 2022 eLearning). If the problem persists and you're in the right, you ought to report to HR depending on what is being said.
Confronting the TM yourself and having it escalate especially in front of other TMs will result in a corrective action or a disciplinary action.
