A National Rifle Association executive in Texas has come under fire for suggesting that a South Carolina lawmaker and pastor who was slain with eight members of his congregation bears some of the blame for his opposition to permitting concealed handguns in church.

Houston-based lawyer Charles Cotton, listed as a national NRA board member on the gun lobby's website, made the comments in an online chat room he administers called texaschlforum.com, a discussion board devoted to gun rights and firearms issues.

In an online thread about Wednesday night's mass shooting at the Emanuel African Methodist Church in Charleston, Cotton said that one of the nine people slain, church pastor and Democratic state Sen. Clementa Pinckney, had voted against legislation in 2011 that would have allowed concealed possession of handguns in restaurants, day-care centers and churches.
