Ken Blackwell, tapped last week by President-elect Donald Trump to head domestic policy during the businessman's transition to the White House, has made anti-LGBT statements for years. Among them: Homosexuality is a sin, and gay people, just like petty thieves and fire-setters, can be rehabilitated.

The Ohio politician has long endorsed a controversial mental health practice known as conversion therapy or reparative therapy. The goal is to cure a person of his or her homosexuality, and in the case of transgender people, to reaffirm the gender into which they were born.
