Cook has been called a “champion” of the movement by Texas Alliance for Life after helping advance a bill requiring sonograms before abortion through his committee in 2011. He also supported 2013’s House Bill 2, which prevented most abortions after 20 weeks of pregnancy and required doctors who perform abortions to have admitting privileges to hospitals within 30 miles.

They are challenging two key safety components of HB 2.
