Walker approved the law in 2013. The vast majority of the media coverage has focused on the fact that, in a recent interview with conservative radio host Dana Loesch, Walker called ultrasound technology “cool” — pointing out that ultrasounds allow people carrying wanted pregnancies to see an image of their unborn child.
