My suggestion is to document all activities and behaviors from those people. Also, try to keep your distance from them as much as possible.
If you have to talk to them or work around them, then keep your conversations limited to the job( no small talk and never discuss personal matters), remain calm yet professional and take notes of any questionable comments and actions just in case you may have to report them to HR or management.
If you can get witnesses of any questionable behavior, then ask for written statements or gain signatures from them on your statements/documents.
In essence, watch your back and cover your ass!
