Texas state Rep. Phil King is calling for a full investigation of late-term abortion doctor Douglas Karpen, Christian News Service reports. The call for an investigation comes after King viewed a video recorded by the pro-life group Life Dynamics, in which three of Karpen's former employees admitted to participating in numerous instances in which babies were born alive and killed during abortion procedures at his Houston clinic. Life Dynamics officials said the actions of Karpen were not much different from the actions of Philadelphia abortionist Kermit Gosnell, who was recently given a life sentence for his crimes. Rep. King informed Life Dynamics that his office mailed the DVD to the homicide division of the Houston Police Department, as well as letters to the executive director of the Texas Medical Board and the commissioner of the Texas Department of State Health Services, requesting a full investigation. The letters were co-signed by 20 Texas lawmakers. "We strongly support a full investigation into the allegations of Dr. Karpen," King wrote. "As a state, we must ensure that the health and safety of women and children are being protected by laws and regulations in place." Mark Crutcher, president of Life Dynamics, said, "If the abortion lobby thinks this issue is going away, they are literally whistling past the graveyard." Texas Lt. Gov. David Dewhurst has demanded a full-scale investigation into Karpen, and the Texas Department of State Health Services said of the investigation, "This is a very high priority for us."
