The 1973 Supreme Court decision established the right to abortion.
Hundreds of anti-abortion activists are gathering in Topeka for workshops and prayer services Tuesday. They also plan to rally outside the Kansas Statehouse featuring Gov. Sam Brownback, a Republican who signed tough, new anti-abortion laws during his first two years in office.
Much to the dismay of abortion-rights advocates, the pattern in Kansas has been repeated in other states.
Meanwhile, the anti-abortion group Kansans for Life plans to ask state lawmakers to enact legislation ensuring Kansas doesn't finance abortions, even indirectly, through tax breaks.
