A Kansas woman allegedly attacked a teenage pro-life canvasser when the student knocked on her door Sunday. The student, Grace Hartsock, was going door-to-door to turn out Kansas voters for a Tuesday referendum on abortion law. The incident occurred when she approached a home in Leawood, according to Students for Life, the organization with which Hartsock was volunteering. Hartsock says a woman answered the door and politely stated she was not interested when she learned why Hartsock had knocked.
