Latham is one of the largest, most prestigious, law firms in the country. I have never read anything about them being tied to derpish activities, although in any large BigLaw firm, there will be some partners, especially in places like NY, DC and SF, who are derps. But they are not Perkins Coie, which seems to be wholly owned by the deep state.
Until you read that their phone number was connected to Susan Rice's email.
