Back in the 70s they had a huge effort to infiltrate covert operative members into a wide swath of bureaucracies. It started with the IRS but included stuff like DOJ, Coast Guard, SS admin. They were looking to get tax exempt status and also harness the government to harass and destroy opponents and ex members.
From the Wiki page...
Operation Snow White was a criminal conspiracy by the Church of Scientology during the 1970s to purge unfavorable records about Scientology and its founder, L. Ron Hubbard. This project included a series of infiltrations into and thefts from 136 government agencies, foreign embassies and consulates, as well as private organizations critical of Scientology, carried out by Church members in more than 30 countries. It was one of the largest infiltrations of the United States government in history, with up to 5,000 covert agents.
As effective as they were it would not surprise me if they were either co-opted, merged into or used by the cabal.

2) The name of the operation which, presumably, accomplished this.
