INDIANAPOLIS — Then-Indiana Gov. Mike Pence faced a firestorm of criticism three years ago after signing a “religious freedom” law critics decried as anti-gay. Now emails released this week to The Associated Press illustrate similar backlash from fellow conservatives when the eventual vice president agreed to change the law in the face of widespread boycott threats. “Indiana is fronted by a coward,” reads a March 31 email to Pence’s office, which was among more than 1,400 pages of documents obtained under Indiana’s public records law.
