"Women’s ability to pursue education and employment opportunities has been greatly enhanced by the ability to have autonomy over their own bodies, something that men enjoy despite the fact that they share 50% of the responsibility for the pregnancy but often time 0% of the consequences," said State Rep.

Mike Lee, a Republican from Utah.
