If you don’t know what Scientology is, just Google it.
Via Smoking Gun:
Since 2001, the Trump foundation’s tax returns contain a single donation that is identifiable with a 9/11 charity. In 2006, Trump gave $1000 to a controversial Scientology program that administered treatment to firemen who inhaled toxins while working on the World Trade Center pile. The New York Rescue Workers Detoxification Fund, co-founded by actor Tom Cruise, relied on a “Purification Rundown” invented by L. Ron Hubbard, the crackpot founder of Scientology.
In recent campaign interviews, Trump–who has long delighted in viciously denigrating opponents and critics–has sought to portray himself as a candidate who cares.
